Perry returns to his office late one night and finds an attractive woman climbing into his balcony window. She claims to be Virginia Colfax, the secretary of Ed Garvin who has an office next door to Perry's. Ms. Colfax says that she climbed into Perry's office in order to escape from Garvin's hot tempered wife but Perry later learns that Garvin is married to two women. Garvin and second wife Lorrie are sent to Mexico by Perry until he can clear up the matter but when Garvin's first wife, Ethel, is murdered there's an even bigger mess on the scene. And just who in the world is Virginia Colfax, the woman climbing in the window?
