 Attorney Ned Murray wins traveling salesman Lew Rydell a not guilty verdict in a murder trial. An hour later, Rydell tells Murray that he murdered the delivery boy, because he flirted with his wife, Melanie. Murray wants justice and threatens to go to the D.A., contrary to the admonishments of his senior partner, Mr. H.E. Osterman, and Osterman s daughter, Karen, Murray s fiancée. Murray also confronts Melanie about Lew s guiltiness, inflaming Lew s jealousy. Murray has a friend, Tony Hardeman, who offers to personally administer capital punishment to Lew. Murray discusses the case with Judge Arthur, and decides to leave Lew alone, but rushes to the Rydell apartment, only to discover that Lew has killed Tony. Murray offers to defend Lew in his next murder trial.
