Dan Willis is the dominating mind of a band of diamond thieves. Corey Houston, an importer, purchases several wonderful gems. A fight in a saloon has resulted in an innocent man being accused of murder of a “squealer.” Drunk, he sprawls over a table while the real murderer places a revolver in his hand. Peggy tries to arouse him to make his escape, but they are discovered and taken into custody. Jane Lowe, a crook through circumstances, learns of her brother’s arrest on a murder charge, just as she determines to “go straight.” Willis pushes his advantage and she says she will steal the diamonds from Houston on condition that Paul is freed. For the purpose, Jane takes a suite in Houston’s apartment. He is attacked in the park and Jane, arriving at the right moment, takes him home. A friendship ensues and Jane asks if she may bring her uncle to see the gems. As Houston is called from the room, Willis orders her to put the gems in a wine glass. Recalling her brother’s plight, she obeys. Houston returns to the room and begins the search just as officers surround the house, and Jane turns over her wine glass, depositing the gems on the table cover. The fact that Willis is the murderer is discovered, and Houston, Paul and Jane find happiness together.
