Jack Ryan is a young Vietnam veteran with a criminal record, who gets fired from his job as a migrant laborer on a California produce farm run by the mean-spirited camp manager Bob Rodgers. Ryan then meets and teams up with the seductive Nancy Barker the secretary and mistress to the unscrupulous owner Ray Ritchie. When Ryan takes another job as a cleaner at a local motel owned by Sam Mirakian a local justice-of-the-peace, Nancy again approaches Ryan to help her rob Ritchie's safe in his house which allegedly has $50,000 of payroll money. Ryan reluctantly agrees to help with the heist, but becomes highly distrustful of Nancy, suspecting she may double-cross him to keep all the money for herself, and vice versa with her over him.
