Herbert Wood, a confidential clerk, is in love with Julia Dale. Mr. Dale approves of his suit for his daughter’s hand, but Julia’s mother favors Don Wallace, who poses as a society man, but in reality is the leader of a notorious gang of thieves. Affiliated with Wallace is Olga Strogoff. Wallace plans to discredit Herbert. Wallace and Olga both attend the reception given at Dale’s residence. Olga steals a watch from an old gentleman and drops it out of the window to the waiting gangster. Then she adroitly unclasps and removes from Julia’s neck a pearl necklace. Herbert drops a card-case. Wallace picks it up, and, after enclosing the necklace taken from Julia, puts the card-case back in Herbert’s pocket. The old gentleman discovers the loss of his watch and Julia the loss of her necklace. Mr. Dale telephones to the police station, and Detective Lamar responds. Wallace announces that he knows Herbert to be the thief, as he saw him put the necklace in his coat-pocket. The detective searches him and the necklace is found. The arrest of Herbert is stopped by Mr. Dale, who declares there must be some mistake. Wallace has apparently accomplished his purpose, as Julia will not recognize Herbert. But there is trouble in store for Wallace, as Olga betrays jealousy, and after trying to get him to desist in his attentions to Julia, she plans revenge. Olga overhears Wallace giving directions to rob the safe of the office where Herbert is employed. Detective Lamar accuses Herbert and arrests him. On the way to the police station, Olga informs the detective of Herbert’s innocence. The den is raided and Herbert, the detective, and half a dozen policemen engage in a fight with gangsters, who are ultimately subdued and led off to the police station. Wallace is shot while attempting to make his escape.
