Skyscraper Souls.

After bank president David Dwight makes a vast loan to himself to build a remarkable skyscraper, his board questions the propriety of the loan. Despite the devotion of longtime mistress Sarah, the ruthless David, while seeking bank mergers to protect his building, tries to seduce Sarah's secretary, Lynn. David then agrees to a plot by a bank board member to inflate his bank's stock and sell short — just before the market crashes.
