This barely-disguised but effective riff on The Thin Man (1934) stars that film's lead, William Powell, opposite Ginger Rogers instead of Myrna Loy. Clay Dalzell (Powell) is a suave attorney fonder of solving crimes than trying cases. His elegant girlfriend, Donna (Rogers) hopes that Clay will settle down and marry her. A friend, Tim Winthrop (Leslie Fenton), approaches Clay with a mystery that the amateur sleuth can't resist. Tim's girlfriend Alice disappeared a year ago. During the performance of a Broadway play, Tim spots Alice onstage, but she disappears again. Clay takes the case and sets up a meeting with a gossip columnist who seems to have the answers, but the reporter is murdered and Clay is suspected of the crime. As Clay puts together the pieces, he comes up with several suspects, including the play's producer, a couple seeking to prove a friend's innocence in a capital crime, and the gangster Jim Kinland (Paul Kelly).
