Jealous Laura McCord suspects that her husband David has been unfaithful to him. One night, she follows him. David's lover Wanda Sutton lives in the penthouse of an upscale apartment building, complete with a security guard at the front desk in the lobby. Laura is so jealous that, upon her arrival, she pulls a gun on the security guard and threatens to shoot him if he doesn't allow her access to the building. So the security guard lets Laura take the elevator to the penthouse and promptly calls the police. Wanda Sutton is the one person to witness the unpleasant scene between Dave and Laura, and she agrees to testify against Laura in court. But when David is indeed shot to death and Wanda disappears, Laura claims innocence. Ben and Julie soon embark on an eventful trip out of the county. It is fraught with bad luck as things go wrong. A red paint stain on a sports jacket provides a vital clue in unmasking the real killer. Judge Irene Sawyer presides.
