Cheating Cheaters
Nan Carey becomes a member of a group of jewel thieves who pretend they are the wealthy Brockton family in order to gain the confidence of real high society families. While traveling, Nan (using the name Ruth Brockton) attracts the romantic attention of Tom Palmer, who turns out to be one of the Brocktons' neighbors. While attending a tea party thrown by the Palmers, the Brockton gang tricks the Palmers into inviting Nan to stay with them while the rest of the Brocktons are supposedly visiting Chicago. The Brocktons expect this ruse will allow them to steal the Palmers' jewelry. It is then revealed to the audience that the "Palmer family" is another group of thieves, who are planning to steal the Brocktons' jewelry while the Brocktons are out of town. Thinking the Brocktons have left, the Palmer gang slips into the Brockton mansion, but are captured by the Brocktons. Meanwhile, Nan has gone to the Palmer mansion to burglarize it. Upon her return, the two groups each realize the other is a criminal gang, and they decide to join forces. Their planning is interrupted by detectives from the Ferris Detective Agency, who capture the combined gangs on behalf of the insurance companies for their past victims. Nan is revealed to be Ruth Ferris, head of the agency, who has been working undercover posing as a thief. Because her love for Tom is real and not just part of her cover, she offers him the opportunity to confess and join her agency rather than be turned over to the police.
