Drifter mechanic Tom Price (Reed) lusts after seductive Marilyn (Dorne), the young wife of ill-tempered garage owner George Saunders (Dwyer). Assuming (correctly) that Marilyn is fooling around with his employee, Saunders angrily confronts him. Defending himself, Tom accidentally kills his boss. Marilyn helps him to cover up the crime - the inquest verdict is "accidental death" - and they begin a new life together.
