On the wharfs of San Francisco, saloon girl Toy, also known as Mary, lives over Mother Bright's bar. When Como Murphy, a fugitive from the law, hides in her room, she falls in love with him. He explains that after he spoke out about the rights of man to a crowd, a riot ensued, during which a policeman was killed. Como took the gun from the killer, but is thought to be guilty of the crime himself. Como, who reciprocates Mary's love, spends the night with her, but leaves to keep her out of danger. He joins the crew of a ship sailing to China after he is befriended by Turk, a big lumbering sailor who is also in love with Mary. Each man is unaware that they love the same woman.
When she can't support her illegitimate child, an abandoned young woman puts her up for adoption and pursues a career as a torch singer. Years later, she then searches for the child she gave up.
With a sparkling script by Leslie Charteris, creator of "The Saint" - the latest crime wave has Scotland Yard baffled. Commissioner Hope (Sir Guy Standing) sends two of his officers (Billy Bevan and Charles McNaughton) to the Midnight Club to check up on a couple of shady characters - Colin Grant (Clive Brook) and Arthur Bradley (Allan Mowbray) and a girl, Iris Witney (Helen Vinson). There have been a number of jewel robberies around town recently, but, unknown to the police, these three have the perfect alibis!!! They have found "doubles", and while they are out committing the robberies, their doubles spend the night at the club, confusing the two officers who are on their tail.
