Hawaii Five-O

Israel's celebrated Nazi-hunter Yuri Bloch has apparently been killed in Honolulu while trying to gather information about a war criminal named Emil Klaus. Knowing the Bloch would only have come to Hawaii if a former Nazi were hiding there, McGarrett and Five-O conduct their own search for Klaus -- while Bloch's partner lies badly wounded in a safe house, and the woman caring for him does what she can to assist while undercover.

During a stop off on a bird-watching expedition, tourists photograph an old sugar mill. They don't know that the mill is a front for a gold-smuggling operation and that one of their photographs has caught the leader through a window. The leader sends a pack of goons to kill everyone in the tourist party and steal their film. McGarrett and a newspaper journalist, who got hold of the pictures, must try to identify the man in the picture and take down his operation before he gets them.

Paul Burke guest stars as attorney David Lawrence, a political candidate whose promising bid for the U.S. Senate is endangered by the murder of a man who tried to blackmail him. Although Lawrence swears he knows nothing about the murder, he admits that the dead would-be extortionist did have knowledge about him that could have destroyed his political future.

The series concludes with the final showdown between McGarrett and Wo Fat. Three scientists who have disappeared have one thing in common, they all attended a symposium on possible space-based, laser defense systems. McGarrett impersonates a fourth scientist, Dr. Elton Raintree, who attended the same gathering and is soon abducted. Wo Fat is behind it all and wants the scientists to complete their work and produce such a device.
