The Wayward Bus (1957)

Alice Chicoy (Joan Collins) is the wife of driver Johnny (Rick Jason). He owns a small and rundown little bus that makes side trips. Alice is the owner of a little restaurant and likes liquor a bit too much. Unhappy with what has become of her life, she decides to "surprise" her husband mid-way through his bus trip. Among the passengers, Camille Oakes (Jayne Mansfield) is the shamed burlesque dancer on the way to a well-paying job in San Juan. Camille gets caught up in a flirtation with traveling salesman Ernest Horton (Dan Dailey). Most of the story takes place on the charter bus. Slowly making their way through a treacherous California mountain region, the passengers undergo a variety of life-altering experiences. The journey has its most profound effects upon the iconoclastic salesman and the lonely stripper.
