When Jim returns to his hometown of Norville to donate family property to the community, he finds it plagued by a serial killer. Jim secretly brings in Barney to help investigate. A disturbed Vietnam vet is the suspected killer but Jim and Barney figure out he's innocent and get him out of jail one step ahead of a mob, then call in the rest of the IMF team to find the real killer.

Reese Dolan is the new Syndicate heroin distributor on the East Coast. Dolan uses an island base off the coast of northwest Africa and is going to use it as a distribution point for heroin into the U.S - the IMF must identify his overseas opium source and get the evidence to convict him. Dolan is being financed by an underworld figure, Madame Renada, whom he has never met, so Jim and Barney fly him and his men not to the island but to a lookalike off the coast of Georgia, where Casey assumes the role of Renada. Reese calls his distributor in Istanbul and the IMF has the delivery plane taken into custody. An IMF flyer makes the delivery which Dolan apparently converts to heroin and sends on its way, while Reese's supplier, Hajii, suspects a double-cross when his pilot doesn't return and calls Dolan's distributor, Cleff. Willy tries to sell heroin to Clegg and then is ""forced"" to tell that Dolan still has it, then lead Clegg to the fake island. Dolan finds out he still has the opium, and

Syndicate man Jay Braddock has corrupted promoter Paul Mitchell into working with him - they had middleweighter Loomis killed when he refused to throw a fight and the IMF must bring both men to justice. They do so by convincing Mitchell that his partner plans to kill him. Barney and Jim steal $37,800 from Braddock and then as a rival mob offer the partners the same amount to buy out their fighter Novick. Braddock decides to have Novick killed but the IMF intercept the call and send in Jim as the hit man. He ""kills"" Novick with a firebomb along with Susan Mitchell (actually Casey in disugise), the promoter's daughter. Mitchell tries to back out as the IMF pressure him, but Braddock messes things up by offering to kill Jim to reassure Mitchell. He manages to escape and they arrest both men.
