Jealousy.

Vamp Anne Baxte marries for money but when her old suitor marries for love and is happy, she becomes insanely jealous. Determined to ruin his life, first she tempts the wife with a lounge lizard. This doesn't work, so she temps her former sweetheart by offering him her husband's business secrets. Unfortunately Ann's husband (George M. Adams) overhears the conversation and not only does he ruin the young man in the stock market, he also tosses Ann out of the house. The film ends bitterly for all concerned.
