In 1993, Michael Jordan left basketball for baseball. This movie is arguably the best thing to come out of it.
How does he get back in the game? He's dragged in by a bunch of Looney Tunes characters who have challenged cartoon characters named the Nerdlucks. When the Nerdlucks steal the talents of professional players and turn into the MonStars, and the Looney Tumes must set about recruiting their own ringers - namely, Jordan (and Bill Murray).
Basketball like you've never seen before, and won't again.
