Two basketball fans, whose enthusiasm overwhelms their intelligence, come up with a new but legally problematic way of helping their favorite team in this comedy. Physical education instructor Mike O'Hara (Daniel Stern) and plumber Jimmy Flaherty (Dan Aykroyd) are close friends and obsessive followers of the Boston Celtics; to them, the Celtics are everything, to the point where Mike's marriage is falling apart because his wife can't deal with his mood swings, hinged as they are on the Celtic's fortunes. One night, with the Celtics and the Utah Jazz tied at three games each in the NBA championships, Mike and Jimmy spot Lewis Scott (Damon Wayans) in a sports bar. The star player with the Jazz, Lewis is known to sink up to 50 shots a game, and his talent on the court is exceeded only by his arrogance. Emboldened by alcohol, Mike and Jimmy start buying Lewis drinks, posing as Jazz fans; the next morning, they wake up hung over to discover that they kidnapped Lewis while drunk, and he's tied to a chair in Jimmy's living room. Neither of them planned on doing anything like this and at first they think they ought to let him go. But then again, if Lewis can't play the final game of the championship series, the Celtics chances look a lot brighter. Former Celtics star Larry Bird has a cameo as himself; as do sports heroes Bill Walton and Deion Sanders.
