Self-made millionaire Thornton Mellon owns a chain of tall and fat clothing stores. After divorcing his philandering wife, he enrolls in college to keep his son from dropping out. Thornton’s invasion quickly turns the campus into a non-stop party zone, and he even helps the diving team win their big meet. Along the way, he rubs a business professor the wrong way, tries to rub a sexy literature professor the right way, and meets a post traumatically stressed history instructor.
