Drunk upper-class Jimmy Martin saves complete stranger Mary Smith from being sent to jail by backing up her story that she was waiting for a man who was going to marry her when she was arrested at a street corner. The suspicious judge offers to unite them on the spot, but Jimmy takes him up on it. When he sobers up, he falls in love with her, despite already having a fiancée. When his mother finds out, she threatens to have his income cut off (he will not gain control of his fortune for two years). This causes a misunderstanding. Jimmy comes to believe that Mary was interested only in his money when Mary offers to let him out of the marriage, whereas she has really fallen in love with him and merely has his best interests at heart.
