 Kirk Bennett is falsely sentenced to death for killing blackmailer Mavis Marlowe, ex-wife of nice-guy drunk Martin Blair. Bennett s stand-up wife Catherine tries to prove him innocent, enlisting the aid of Blair, who falls in love with her. Bennett s execution draws near as the two pose as piano player and singer, trying to get the goods on sleazy nightclub owner Marko, a prime suspect. Failing to nail Marko, Catherine goes off to meet with her husband, scheduled to die the next morning, and Blair slips into an alcoholic stupor before the real killer is revealed.
