Drive a Crooked Road (1954)

Eddie Shannon is an undersized, sports-car mechanic who dreams of racing an expensive car in a European meet. He meets and falls in love with Barbara Mathews, and thinks she loves him. She introduces him to Steve Norris and Harold Baker, who ask him to drive the getaway car in a bank robbery they are planning. He refuses, but changes his mind after some gentle persuasion from Barbara. The job is pulled off and, following a wild getaway, Eddie learns that Barbara was just using him and that Steve and Harold have plans to kill him. Gritty retribution is just around the corner.
