Ernest takes a job with a cleaning service, and soon seeks to join his co-workers' basketball team, "Clean Sweep", as they compete in the city league tournament. He is reluctantly accepted by the team, but given only a minor role as their cheerleader and mascot. In his despair, he is visited by an angel, played by basketball legend Kareem Abdul-Jabbar, and given a pair of magic shoes.
When an injury to a key player leaves the team desperate for a replacement, Ernest is given an opportunity to play. In the process, he discovers that the supernatural shoes have imbued him with super-speed and the ability to fly. Armed with these extraordinary abilities, he leads the team to a series of victories leading ultimately to a showdown with the NBA's Charlotte Hornets. As the city league tournament champions, Clean Sweep earns the right to play an exhibition contest against the Hornets, but suffers turmoil as Ernest's team-mates soon grow weary of his ball-hogging antics.
