They soon run into trouble, however, in the form of two sets of rival gangsters who want to break into the hotel safe; also, Mary's mother, Rebecca Marsh, wants her to marry wealthy lawyer John Blackwell, although Mary has fallen in love with Wilbur. And while she takes an instant dislike to Wilbur, Rebecca falls for Ganzy. Adding to the complications is the fact that Blackwell is actually in league with the gangsters. The finale involves nighttime runarounds and a shoot-out in the hotel. During the pitched battle between the rival gangs and the police, Boswell and Ganzy save the jewels, after which Ganzy marries Rebecca, and then gives away Mary at her marriage to Wilbur.
