Laura Venning in saving the life of Detective Martin's child, wins the friendship of a man of cunning who serves her when she is imperiled through the attentions of an adventuress, who uses her to revenge herself upon Miss Vennlng's brother. Jack Venning in a moment of insane wagering gives a check for $5,000 to secure a gambling debt. The dashing Jack is admired by Mrs. Romano, a society adventuress, a passion that is not reciprocated and turns her fondness to hatred. She overhears Jack's confession to his sister concerning the check and his plea for $5,000 to save him from prison. The hostess of the evening has a pearl necklace of great price that is broken, so she puts it in a crystal jewel box in her boudoir. The wily and revengeful widow gets the necklace and places it in the vanity bag of Laura. The latter, disconcerted by her brother's story is about to leave the house when the loss of the necklace is discovered, and Laura is accused of the theft. The officers, Mrs. Romano adroitly eggs them on and calls Martin the chief of detectives on the case. How he discovers the real thief is one of the cleverest bits of picture work in recent film plays.
