An opera singer is sick. LEUNG TSAN, a cook in the opera troupe, is asked to play the role of LUI PO as a replacement. Manchurian LUNG FOR PUI HAK, who is in the wing-room watching the play, finds TSAN’S Kung Fu very impressive. Later, he challenges TSAN in the marketplace to a fight. WONG WAH PO, TSAN’s Kung Fu master, comes to his rescue. PO uses a trick to make TSAN confess his love for CHEUNG KIN HEI, on whom TSAN has a crush. He even selects a day for their wedding without their consent. HAK enters the troupe by force and demands to fight with PO. To make HAK leave as soon as possible, PO lets HAK defeat him intentionally. PO is seriously injured. HAK says that there is nothing really special about Wing Chun Kung Fu. This irks TSAN to the core and he goes to HAK for a fight. He is defeated, nevertheless. He has left the engagement token that HEI has given him there. He breaks in HAK’s house to take it back……

As told by PO, TSAN asks TAI whether he remembers what happened on the first of October years ago. TAI puts up a long face when he hears this, and agrees to put up TSAN and YEE. KWAI takes HEI to visit CHAN LOK FUNG, the person-in-charge of the biggest grocery in Foshan. FUNG has once saved HEI’s life. FU takes a woman whom owes him money as his concubine by force. HEI, who sees this, goes up to intervene. FU is displeased with what HEI has done. He tricks HEI to a wing-room in a teahouse and tries to rape her. HEI hits back; FU is badly injured. After knowing that FU has kidnapped HEI, KWAI goes to LOK for help. Together they go to Sam Shing Tong to demand the release of HEI. FU vows to take HEI as his concubine. KWAI can do nothing but lies that HEI is LOK’s fiancee. LAI TIN HUNG, the grand master of Sam Shing Tong, agrees to release HEI eventually. FU stirs up trouble in LOK’s wedding party and challenges HEI to a drink competition……

TSAN enters LOK’s room and beats him up. HEI stops him. She tells him the reason why she marries LOK. CHAN YUK HING, the younger sister of LOK, listens to her younger brother, CHAN HING FUNG, and believes that HEI marries LOK for his money. She makes things difficult for HEI. YEE smells opium from the broken bamboo lot that TSAN is holding in his hand. Following this clue, TSAN investigates Lok Fung Hong. LUI BING, the brother-in-law of LAW KIN who is the leader of the porters, makes an appointment with TSAN to meet up at Mountain God Temple at night. FU kills BING and takes away from him the receipts for the smugglings of white silver of Sam Shing Tong. TSAN does not see BING at the temple when he gets there. He sees a person dressed in black trying to rape a woman instead. TSAN comes to her rescue and comes to know LIN YUNG, the new police chief. LOK goes to the teahouse to collect debts……

LOK writes his will and dies. In the hall where LOK’s memorial service is held, HUNG demands HING to hand over Lok Fung Hong to him to repay his gambling debt. HEI takes out LOK’s will and tells him that she is now the person in charge of Lok Fung Hong. She also declares that HING’s debt has nothing to do with Lok Fung Hong. The police have found BING’s dead body. HEI fins some bruises on the body. She presses some paper on the bruises to leave some imprints. TSAN suspects the killer is someone from the martial arts world. TSAN goes to different Kung Fu gymnasiums to have Kung Fu contests with people in order to find out the killer. FU takes liberties with women. YUNG gives him a good lesson. FU ambushes YUNG later on for revenge; TSAN shows up and saves YUNG. Lok Fung Hong no longer delivers goods for Sam Shing Tong. HUNG is very angry. He asks HING to deal with HEI……

HING speaks ill of HEI in front of SHUN, accusing HEI of cheating LOK’s money. Feeling wronged, HEI gives the seal of Lok Fung Hong to SHUN and leaves. SIU FU YUNG, the apprentice of TAI, helps TSAN in arresting the person who killed BING. He therefore goes to different Kung Fu gymnasiums for fighting contest. As a result, he is injured. Looking at his bruises, TSAN suspects that BING was killed by FU. FU TSAT HO YUET, the daughter of TAK, comes to Foshan to arrest the rapist. FU peeps at YUET when she is taking a bath. He runs away when he sees TSAN is following him. TSAN is therefore mistaken by YUET to be the rapist. Listening to the slanderous talk of HING, SHUN fires KIN. Later, KIN gets beaten up. The porters think that it is the work of SHUN and so kidnap SHUN and gives him a brutal beating. HING begs HEI to save SHUN. HEI says that she will not take back Lok Fung Hong unless SHUN agrees with the three conditions that she sets……

FU is about to rape YUET when YUNG and TSAN show up to her rescue. FU is locked up in a jail. A local official, LUK, as told be HUNG, bribes YUNG to release FU. YUNG takes he bribe on the condition that FU must plead guilty by making a sign in lieu of signature. FU is an illiterate; he does not know at all the piece of paper is in fact a confession of his killing of HAK. YUNG sentences FU to death o execute FU for his escaping from the jail. This way, YUNG hopes that TSAN would stop his investigation. In order to give SHUN a lesson and to squeeze him out of money, YEE lies to him that TSAN will take him his apprentice. As told by her servant, Uncle KAI, YEE comes to know the past of TAI, his wife and his daughter. She firmly believes that WONG TAI MA, who died when saving her life, was TAI’s wife. To repay WONG TAI MA’s kindness, YEE shows TAI the jade pendant that WONG TAI MA gave her……

SHUN goes out with some bad friends of his. HEI is so angry that she punishes him with the family rules. SHUN is vexed. He swears to earn ten taels of silver home in three days. SHUN’s bad friends isolate him as soon as they know that SHUN is down on his luck. SHUN dines at a restaurant but is unable to pay the bill. He has to clean up the leftover for the boss in return. SHUN, who is moneyless, with the help of KIN, has finally found a job. PAU laughs at the down-and-out SHUN. YUNG, who is passing by, cannot bear to see SHUN being bullied. He volunteers to take three punches of PAU for SHUN. What’s more, he puts SHUN up at TAI’s place. The next day, with the help of YUNG, SHUN manages to collect ten taels of silver before sunset. Knowing that SHUN has turned over a new leaf and wants to learn Kung Fu, HEI asks TSAN in private to take SHUN as his apprentice. YEE bumps into TAK in the marketplace. TAK came to Foshan to look for YEUT……

YEE thinks that TAK came to arrest her. In order not to involve TSAN and the others, she decides to flee. As she does not have any money, she steals the pearl-hairpin of TAI, which he used to wear when he was acting, and sells it. TAI celebrates YEE’s birthday with her. He gives her the presents that he has prepared over the years. YEE is touched. She wants to redeem the pearl-hair-pin and give it back to TAI but she is discovered by TSAN. YUET’s cousin NAP LAN CHING KWONG have arrived in Foshan. He invites YUET to go picnic with him but he takes with him a group of subordinates on the day. YUET finds him a very boring guy. She then walks to the riverside on her own, where she sees TSAN being with a woman. Meanwhile, she remembers that TSAN has once peeped at her in bath and so asks KWONG to give TSAN a lesson. The yearly Firecrackers Assembly is around the corner. Winning at the event means a lot to Lok Fung Hong……

YEUT thinks very highly of TSAN after the incident. KWONG knows then that YUET has fallen in love with TSAN and he is a bit displeased. With the pretext of learning from each other, KWONG invites TSAN to a kung fu fighting. TSAN gives KWONG a pounding on the chest. He is surprised that KWONG absorbs the strength of his attack. TSAN loses in the end. He admits defeat and leaves. In order to thank TSAN for saving her life, YUET delivers loads of expensive gifts to YEE’s Lodge. TSAN refuses to take them and return them all. YUET is furious. HEI finds that the SHUN that SHUN is delivering has something to do with Sam Shing Tong. She goes to the warehouse for an inspection of the goods. She furthers returns the down payment to the owner, claiming that she does not want to have any connection with Sam Shing Tong. PAU learns that YUNG is the reason that his business is spoiled and that his down payment is returned……

HEI points out that the goods are entrusted by a merchant called MAN TAK. TAK has gone missing since nevertheless. TSAN follows MAN TAK’s wife and finds TAK eventually. TAK is arrested. LIN YUNG worries the release of HEI will bring HUNG trouble. He therefore tells HUNG that he is a right-hand-man of TAK’s. TAK is poisoned to death after admitting guilty. HEI believes that there is something fishing going on. Some opera singers pay a visit to TAI. YUNG is requested to sing a song. YEE fears that YUNG will make an exhibition of himself and so sings for him behind the scene. Seeing that YUNG does not have talent for singing, TAI decides not to force him anymore. TSAN keeps asking about what happened to PO and TAI on the first of October years ago. TAI has no choice but to tell him everything. He also teaches TSAN the Six Touch Half Stick of WING CHUN Sect. YUNG asks SHUN to give him a hand and write YEE a letter……

YEE mistakes that SHUN has asked YUNG to hand her the love letter. She pretends to be good to YUNG so as to incite SHUN. YUET has stolen the signboard of Yee’s Lodge in order to force TSAN to go out and have fun with her. TSAN leaves Yee’s Lodge as soon as he has got back the signboard. YUET follows him. Seeing that TSAN and HEI behaving rather intimately, she goes to the CHAN’s and scolds HEI for being a whore. HEI explains to her family members that her marriage with LOK is only a fake one. SHUN does not believe her though. He knows HEI is telling the truth only when Mother HO, a servant, supports HEI. He makes up with HEI and asks her to go back to Lok Fung Hong and to be in charge of it. TAI and KWAI have come up with a treatment that helps people quit opium. They hand it out free on the street. People in Sam Shing Tong is unhappy about this and they go and make trouble at KWAI’s medicine shop……

TAI comes to the rescue of YEE, YUNG and SHUN. When the three have all gone, TAI stays behind to fight with HUNG’s subordinates. To his surprise, there is only LIN YUNG. TAI fight with LIN YUNG. Unwilling to kill TAI, whom he knows is innocent, LIN YUNG lets TAI leave. KWONG learns about the incident. He follows TAI to PAK FA WOODS with a view to killing him. TAI has taken in a large amount of pollen, so much so that he has an asthma attack. TSAN is utterly devastated when he knows that TAI has died in PAK FA WOODS. LIN YUNG has deliberately covered the fracture on the body of TAI. HEI therefore suspects his is the one who killed TAI. TSAN questions LIN YUNG about this. LIN YUNG confesses that he has found a piece of agate on TAI’s body. He deduces from this that killer is a Manchurian. TSAN begins to investigate YUET. Feeing that she should be responsible for TAI’s death, YEE plans to leave Foshan……

YUET suspects that the agate comes from KWONG’s dagger after learning from TSAN the shape of the agate. YUET makes KWONG drunk and takes away his dagger for a look. KWONG, nevertheless, has seen through his plot from the beginning. He gets back the agate from LIN YUNG, puts it back onto the dagger so as to alleviate YUET’s suspicion. TSAN learns from CHO SAM BIU, the supreme master of the Pentagon Sect, that FU cannot be the one who killed HAK. TSAN finds the whole thing mysterious. KWONG kidnaps LIN YUNG’s grandmother and orders him to kill TSAN. HEI sees HING stealthily chucks away a packet of edible bird’s nest. She takes the bird’s nest for an analysis and finds in it some Indian Red Flower, a subtle poison. KWAI does not want HEI to put herself in danger in finding out the cause of LOK’s death. So he goes to LOK’s grave on his own. He opens LOK’s coffin and examines the corpse. His act is spotted by PAU……

Unwilling to be used by KWONG to threaten her grandson to work with him, LIN YUNG’s grandmother takes her own life before LIN YUNG. LIN YUNG begs KWONG to let TSAN go, only to be accused of betraying TAK. KWONG kills LIN YUNG. He then announces in public that LIN YUNG has committed suicide to avoid punishment. TSAN does not believe that LIN YUNG would kill himself. He does not believe that he has killed TAI either. TSAN examines LIN YUNG’s body again. He finds on the chest a large bruise, which he recognizes is caused by the Chain of Punches. The police have found KWAI’s corpse in the riverside. It is proved that KWAI has died from falling off the cliff. HEI is grieved. She tells TSAN her suspicions that the death of LOK, TAI and LIN YUNG have something to do with Sam Shing Tong. HING conspires with CHIU, who is a Chinese medicine practitioner. Without her knowing it, HEI has bought some acute poison from CHIU……

TSAN gets hold of CHENG TIN, the subordinate of LIN YUNG, and forces him to release HEI. TSAN promises TIN that he will follow him to the magistrate’s office for a trial. The owner of a private bank and CHIU point their accusing fingers at TSAN. TSAN is taken into custody to wait for his sentence. On the other hand, HEI, YUNG and YEE are put on the wanting list. HUNG sends a killer into the jail to have TSAN killed. Seeing that TSAN kills the killer with the Chain of Punches, TIN firmly believes that he is the killer. After learning from medical books the toxicity of the Indian Red Flower, HEI deduces that it was HING who killed LOK. Unfortunately, she does not have any evidence. HEI goes to find YUET, who is now under house-arrest, for help. YUET lays down a condition in return. YUET has reversed the judgment on TSAN. After that, she asks for TAK’s permission for her to move into YEE’s Lodge. And if he refuses, she will kill herself……

After much effort, TSAN finally manages to persuade HEI into staying in Foshan so as to look into the cause of KWAI’s death. HEI has once promised YUET that she would not marry TSAN and she determines to keep her word. In the vicinity of a cliff near LOK’s grave, HEI discovers an order-token that belongs to Sam Shing Tong. Burnt with anger, she rushes to Sam Shing Tong to check it out. Meanwhile, Lord LUK arrives. HEI requests him to correct the injustice done upon her father. To her disappointment, he is on HUNG’s side. To convince SHUN that it was TSAN who killed his father, KWONG takes SHUN to see the corpses of the boss of the private bank and CHUI. SHUN recognizes that the wounds on the bodies had been made by the Chain of Punches almost immediately. SHUN listens to HING and promises to deliver ceramics for Sam Shing Tong. He also invites Lord LUK to be the witness of goods checking……

SHUN mistakenly believes that TSAN is the cause of his imprisonment. He hates TSAN even more. TSAN and HEI go to the now empty Sam Shing Tong for investigation. They take away some partly burned papers for further investigation. YUET finds some stamps of Prince YEE TAK on the papers. In order to dig further, she pretends to become reconciled with TAK and investigates in KING LAM YUEN. As expected, she discovers that KWONG has hidden HUNG and PAU in the basement of KING LAM YUEN. YUET tells TAK what she has found and asks him to bring KWONG to justice. To her huge surprise, TAK admits to her that he is the mastermind behind the smuggling. He does not let her go as that she cannot inform TSAN. TIN accuses TSAN of breaking in the jail and taking away SHUN. He and his subordinates arrest TSAN. Seeing this, YEE tells them that it was TAK who has HAK killed……

YUET hurries to the Kung Fu competition in time. She discloses KWONG’s plot in public. KWONG throws his spear at TSUI in the chaos. He misses and escapes. YUET advises TAK to surrender. Knowing that he will surely be executed, TAK chooses to take his life in jail. YUET is very sorrowful; she takes TAK’s ashes back to capital for burial. TSAN sees HUNG buying medicine for KWONG’s internal injures. He follows HUNG, with the hope to find the whereabouts of SHUN. Unfortunately, he falls into HUNG’s trap. KWONG makes a mistake and SHUN takes in too much of Five Stone Powder. As a result, SHUN has turned into another person. SHUN enters YEE’s Lodge by force and kidnaps HEI. KWONG leaves a note, demanding TSAN to go to the warehouse to save her. SHUN and TSAN are fighting with each other when KWONG sets fire to the warehouse. The wicked him also pushes YUNG and YEE, who comes to TSAN’s help, into the warehouse and locks the door……

The fire has been burning the whole night through. The warehouse is reduced to ashes. In a pit inside the warehouse, YUNG finds TSAN and HEI, who are still very much alive; all are overjoyed. Facing SHUN and YUNG, YEE is unable to make a choice as to who should love. SHUN and YUNG suggest them settling the matter by a duel. KU CHAI TONG, TSAN’s medical shop, opens for business. TSUI sends a signboard as a gift. KWONG is furious that TSAN has destroyed his future. He challenges TSAN to a duel in the countryside in the evening before TSAN’s wedding. TSAN hopes that no innocent people will get involved in this matter. So he covers this up from HEI and goes to meet KWONG. Using the Stone Breaking Palm, KWONG is able to restrain TSAN’s Six Touch Half Stick. TSAN is in the disadvantageous position. After several rounds of fighting, TSAN finally discovers the weak-point of KWONG. HEI is unhappy about TSAN’s fighting with KWONG……
