Ed Fraser (Howard Duff) returns to Medicine Bow, having served time for robbing the local lumber yard. He had been convicted based largely on Steve Hill's testimony but the stolen $30,000 was never recovered and his unknown accomplice, Helen Blaine (Ida Lupino), whose daughter (Joey Heatherton) Steve has been dating, had escaped. When there is what he perceives as an attempt on his life, Steve makes no secret of the fact he is convinced Fraser is out for revenge. When Fraser is killed Steve becomes the prime suspect. Although he avoids trial due to a lack of evidence, Steve becomes a social pariah and sees that the only way out is to solve the crime.
