Harry Williams, member of the rhythm & blues band Bloodstone, is about to go onstage for a concert when he is hit on the head. The rest that follows is his dream. The four band members become conductors on a train filled with (impersonated) actors and characters from the 1930s such as W.C. Fields, Dracula, and Scarlett O'Hara. For instance 'Jay Lawrence' (q.v.), who gave a brief impression of Clark Gable in _Stalag 17 (1953)_ (q.v.), plays Gable at greater length. Patterned after movies by the Marx Brothers and the Beatles, "Train Ride" features various songs. The thin plot requires the singing conductors to solve a mystery; Marlon Brando is murdering Nelson Eddy, Jeanette McDonald, and others by suffocating them in his armpits. Arriving in Hollywood, the Bloodstone boys are turned into wax sculptures by Brando.

Right before he is to go onstage, a member of the rhythm and blues band Bloodstone is hit on the head and goes into a dream. In his dream, the four band members are conductors on a train full of 1930s actors and fictious characters, including W.C. Fields, Scarlett O'Hara, and Dracula. When a crime is committed, the guys in the band are responsible for solving the mystery.
