On holiday and going to meet Rollin at a mountain lodge, Jim stops off in a small town. However, a young couple drop a package containing a gas gun. Exposed, an old man named Doc takes Jim prisoner. The town is populated entirely by enemy agents and they plan to kill a Societ defector in L.A. Doc shoots Jim with curare and the young couple head off to kill the defector. When Rollin arrives, Doc claims Jim had a stroke and can't be moved, but Jim clues him in by blinking a warning in Morse code. Rollin mobilizes the team. Cinnamon goes in as Mrs. Jim and Barney as her chauffeur, and Willy as a trucker. Together the four of them have to get Jim out and thwart the assassination plot.
