An out-of-work architect meets a married woman who has a business proposition for him. The architect begins to suspect the woman's interest in him is not just financial and may actually be deadly.

Former Coastguardsmen Jim Benson is about to lose his boat when a couple approaches him for a fishing charter. Jim departs just ahead of the Sherrif with drunken Shanks, and his companion Sally (Gates). Shanks takes off into a small Mexican village after a fight with Jim, stranding both Sally and him with no money. Two local men hear of Jim's plight, and offer him money to smuggle a batch of illegal aliens, called Wetbacks, into the U.S. He agrees but is blackmailed into continuing to run the smuggling operation. Afraid, Jim decides to make a run for it, but someone close to him reveals themselves as a US Immigration agent and asks him to assist them in shutting down the smugglers for good.
