Scumbag rings the bell for his IPO, while a Wall Street heiress shorts his stock instead

A Wall Street heiress hides her true identity and marries a man of humble means. She returns to Ohio for a family visit on Thanksgiving, only to be stunned to find her husband has moved his mistress into her private villa. The mistress poses as the lady of the house, runs up debts on her SSN-linked credit and leaves her to foot the exorbitant property tax. Faced with such exploitation, she vows to short his company with massive capital on the day of his Nasdaq listing and crush him completely.
