A Vietnam veteran, whom Thomas distantly knows from a mission they both served on during the war, hires him to supposedly find his missing girlfriend. But unbeknown to Thomas, the man actually has an ulterior motive, and is using him to track down an old adversary with whom he has an old score to settle over the death of an Army buddy...

Mac's latest shady money-making scheme has landed him in trouble with the Japanese Yakuza, so he convinces Rick to buy a sailboat from him, complete with a crew of three Japanese women who barely speak a word of English. Rick is furious when Mac skips town just before the boat is impounded because Mac didn't own it in the first place, leaving Rick unable to repay Ice Pick the $20,000 he borrowed to buy the yacht, now that he can't make the money he planned by renting the boat out for charters. To get Rick's money back and keep the Yakuza and Ice Pick from doing him harm, Thomas sets out across the mainland to track down Mac.
