The violent death of a small shopkeeper brings Supt. Miller into Victor Division and into conflict with Barlow, who has his own solution to offer.

Z-Victor Two gets an alarm call to a jeweller's shop. Sgt. Watt gets the information that leads to an arrest, but the case is not as simple as it seems.

The trail of a walk-in thief leads Smith and Weir to a locked room in Newtown and on to a night in Blackpool - but not to see the illuminations!

Lynch and Steele investigate a break-in at a factory where the night watchman has been attacked and injured. They bring in a man the Newtown police have long wanted to see behind bars. But bringing him in is one thing, keeping him in is another.

A neat operation in car stealing begins to go wrong when the thief tries mixing business with pleasure.

Johnny attacks a man in a pub - the wrong man. Steele and Lynch have to find him before he finds the right man.

Detective Superintendent Miller, aggressive as ever, leads the local Newtown force as they attempt to find a man who has attacked several young girls.

Dick Davis comes out of Walton jail and immediately plans his first job. But after two years in prison Davis cannot match the quality of his planning with the quality of his new accomplices.

Hilda Simmons reports that her car has been stolen. But she omits to tell the police that the man who took it is her husband. Smith and Weir have the task of rounding up the 'thief' only to find that the charge has been withdrawn. However, Sgt. Watt recognises Simmons of old, and soon tumbles to what is happening.

Lynch and Steele are called to a pub fight. Who started it? As Geraghty said: ""Hollis is always starting fights. Too clever for himself this time, though - far too clever"".

A London gang move north. They plan a short and profitable visit to Newtown. Smith and Weir spend a busy night trying to cut down their profits and lengthen their stay.

A quantity of drink and five suits are missing. Steele and Lynch spend a long night looking for the drink while the rest of the Newtown police are at the Christmas party.

Arrest usually pile up at night - except in this case that involves a safe, the Army, a divorce and a potted plant.

Export cigarettes are being imported into the Newtown area. Lynch and Steele pick up some fag-ends of information.

A casual lift as the rain pours down - and for Winnie Parker it means a drive of terror. Her kindness in persuading her husband to pick up a hitch-hiker puts her in danger and gives a long night of anxiety and work for Smith and Weir.

Bob Steele is late for work. And because of this he becomes accidentally involved in a case concerning a petty thief. He is going through the town's shopping centre when a middle-aged woman comes running out of one of the stores, closely pursued by a security guard. She has apparently been shoplifting. But what seems at first sight to be a 'simple case' confronts Steele with the biggest decision of his life. (This was Jeremy Kemp's last appearance as PC Bob Steele.)

The act is sudden, brutal and corroding. The problem facing Barlow is what the victim has done to warrant it.

Lynch goes out on patrol with PC Dave Graham, the former dog-handler who has been chosen to replace Bob Steele. With Lynch missing the companionship of Steele, the relationship between the new pair is not easy. They quickly run into trouble - with each other and with a pair of thieves with an ear to police business.

Cock-fighting is cruel, bloody and illegal. Its promoters have to work in secret, and so do the police in trying to catch the perpetrators.

The trail of counterfeit notes begins in a chemist's shop. Following it is more complicated than Lynch and Graham would ever have believed.

The men want the new club to be peaceful and palatial. John Watt's concern is with the way it is being financed and furnished.

A serious crime has to be reported to Headquarters. Barlow's main worry is that the crime may not have been committed at all.

In an attempt to improve the crime statistics Barlow has Smith and Weir devoting valuable time to the theft of a bicycle lamp and John Watt is set to clear up an affair of lead castings pilfered from a factory. Both seem trivial, but Barlow thinks that they are worth some trouble - and as usual he is proved right in the end.

Despite all the anger and resentment they arouse nothing must deflect Inspector Bamber from the most difficult enquiries of his career - into suspicions that Victor Division contains a policeman who is a thief.

Glossop is a name all too familiar to Newtown CID. His record includes larceny, assault, shopbreaking, gaming and assault on police. So when he escapes from prison and is reported to be back in Newtown Barlow makes it his personal business to find him. But knowing Glossop's reputation, the informers are reluctant to talk.

A big bump in the night and the hunt for the safebreakers is on. But the safebreakers are hunting too - for the expert.

Only when the birds have flown does Z-Victor One get called to the Atlantic Hotel, where a man and woman are wanted for not paying their bill. Barlow has to set snares to catch them.

A mailbag robbery in Newtown and Barlow is in his element as the masterly organiser at the centre of operations. He sends Lynch and Graham to set up a road block, chivvies John Watt into scouting for information and reminds Sgt. Blackitt of the golden rule: ""Can't afford to let things stop or get bogged down"".

""Crimes like this, there's always two, always. I've never known it otherwise"". And DCS Robins is talking about murder.

A vicious bunch of thugs and a young couple in love. Lynch and Graham are involved with both while their own working relationship reaches flash point. PC Sweet and the relative newcomer DC Hicks also get caught up in the action.

The alarm rings and the police dash to the scene. This is the reflex action a clever crook can calculate on - except when PC Jock Weir decides to take charge.

It's the night after a big rugby football match. Lynch and Graham get a surprise when they are sent to investigate a spot of trouble at a pub on the Newtown to Seaport road, for there they find Jock Weir. He is having a drink with friends to celebrate playing on the winning side, but with the arrival of Lynch and Graham the evening turns out to be anything but a happy one.

Fancy Smith's devotion to duty takes him, on his night off, to visit a young offender's father, with results that make him bitterly and furiously angry.

The crew of a merchant ship about to dock at Seaport are looking forward to shore leave. They have money to burn and an itch to burn it in Rosie's Club. When a smallpox scare leads to all leave being stopped, two sailors have other ideas and sneak ashore. Lynch and Graham have to find them to prevent a possible smallpox epidemic.

Cattle are identified by marks on their ears. Sgt. Watt and Z-Victor One have to find their own way of identifying the people responsible for a large-scale fraud.

In soccer mad Newtown tickets for the big match are at a premium. Everyone wants to go, villains and police alike. Con man Johnson has eight tickets to distribute to people who might be useful to him, but mistakenly hands them to Paddy, a fixer who has his own ideas about who to give them to. Lynch and Graham also have tickets and are on their way to the stadium when they come into violent contact with a gang of men in a stolen lorry.

A team of pickpockets and the attempt to track them down leads Jock Weir into serious trouble with the public and with the Chief Constable.

The Coroner's demand for the presence of a witness sends Smith and Weir to a lonely cottage, to be greeted with a kind of violence even they do not expect.
