Caine is accused of murder and must seek out a witness who is a member of a gang of Indian scalphunters, who doesn't want to help him. He must also deal with an Apache warrior who wants to kill the witness for his crimes against the Apache.

A reclusive hermit, Tamo, arrives at the Honan monastery to inform them that the Fukien monastery was attacked and destroyed by a warlord with his cannon, and that he has survivors seeking refuge there. One of the survivors is a woman who wants to become a Shaolin monk. She later reveals the warlord wanted her to be his wife, and she fled. Now the warlord is preparing to attack the monastery and having his cannon brought there.

Caine and the others try to defend the monastery, while the cannon the Warlord SIng will attack them with is still enroute. In the meantime, he must contend with the fact that a woman who wants to become a Shaolin monk and rejected Sing's hand in marriage, has fallen in love with him.
