Perry Mason finds himself the target of an attempt to discredit him while he is in the middle of a major lawsuit. Perry is representing a young woman, Barbara Kramer, who accuses Otis Swanson of stealing her father's intellectual property. Swanson will stop at nothing to win and endorses his nephew Dan's elaborate plan to discredit the famous attorney in court. Using an investigator Dan has located a British sailor, Grimes, who is the spitting image of Mason. He arranges to have Grimes - dressed and groomed to look like Perry - try and bribe a prospective witness. A missing letter will prove Barbara's case but without it Perry loses the case and not only has to defend his reputation but also protect Barbara who continues to involve herself in risky behavior with Dan Swanson trying to find the missing letter. Barbara is accused of murder after Otis Swanson is found dead by Paul with Barbara standing behind a curtain. Written by
