Private eye Mike Hammer probes his long-lost love's death while seeking their daughter.

This movie looks at the last years (not days, as implied in the title) of famous outlaws, Frank and Jesse James. The film opens in 1877 with the brothers trying to settle down after 15 years of thievery. Frank is shown to be a book-loving and family-oriented man, while brother Jesse is a money-hungry womanizer. The movie follows their lives through Jesse's death at the hands of the "rotten little coward" Bob Ford and Frank's death in 1892.
