During an historic Wall Street boom, young MBA Finn Keane gets to perform on the world's stage when he's hired by the investment banking powerhouse Abercrombie, Wirth & Co. His first deal involves the acquisition of Milstien Stores by Kristos & Company. However, as soon as the business is handed over to founder Nick Christanapoulas's ineffectual son-in-law, one of ABC's senior managers, Jack Shane, engineers a risky financing that drives the business into bankruptcy. In the process, Shane demonstrates to Finn how Wall Streeters operate. Finn realizes that the financial world is populated by egomaniacs, and he is determined to help Nick buy back his company. When Shane and his cohorts hear of the plans, they threaten Finn's life and expose his new girlfriend's sordid past, because all along, they wanted to carve up this business for themselves. Little do they know what surprises Finn has waiting for them.
