In 1976, Jackie Moon is a singer who used the profits from his one-hit wonder, "Love Me Sexy," to buy a basketball team in the American Basketball Association, the Flint Tropics, becoming the owner, head Coach, and starting power forward. The ABA Commissioner announces a plan to merge the league with the National Basketball Association, but only four teams will move to the more established league. The Tropics, the worst team in the league, are in danger of dissolving. Jackie argues that the teams with the four best records should be merged and the Commissioner accepts.
Jackie trades the team's washing machine to the Kentucky Colonels for Ed Monix, former backup point guard for the Boston Celtics. The Commissioner reveals that the Tropics will also need at least 2,000 fans at every remaining home game.
Jackie begins to stage extremely desperate stunts, like wrestling a bear named Dewie. The Tropics begin playing better with Monix, as well as the increased intensity of Clarence Withers. Monix takes over as offensive and defensive coordinator and starting point guard, leaving Jackie as the head coach. Monix trains the team rigorously with a play he calls the "Puke" as the players are to run it, until they throw up.
From Monix's training, the Tropics go on a winning run, moving from last to fifth. Jackie gets a visit from the Commissioner. The NBA does not think that Flint has a large enough media market and will not allow the Tropics into the league even if they beat the first place San Antonio Spurs. Jackie admits that he stole "Love Me Sexy" from a napkin his mother wrote on three weeks before she died. Realizing that all his assets are basically stolen, Jackie trades Withers to the Spurs so that he may realize his dream in the NBA. Monix inspires the team to leave everything on the court, while they may not be able to continue the franchise after this season, they have come very far and still have a lot to prove.
Going into the Spurs game, which Moon declares the "MegaBowl", the Tropics are in fifth place and with a win they would make it into fourth, although they have no chance in making it into the NBA. The game begins and the Tropics fall behind quickly. In the closing seconds of the first half, Jackie gets fouled hard by Petrelli while going up for a shot and is injured. Withers decides he has seen enough and rushes in to the Tropics locker rooms with the rest of the team, which angers the Spurs.
During halftime, an unconscious Jackie imagines that he is in heaven with his mother. He apologizes for stealing her song and she gives him a weapon in order to win. On the court, the Tropics reveal their new weapon: the alley-oop. With the return of Withers, it is very effective and he leads the charge. The referee calls the play a foul, but after some persuasion by Jackie and Monix, is soon convinced that it is a legitimate score. The Tropics take advantage of this new strategy and begin coming back. After the Spurs start defending against the Alley-Oop, Monix calls a time-out and calls for them to run the "Puke" with 12 seconds left and down by two points, 115 117. The play gives Jackie the ball, but he gets fouled hard again with two seconds left. Shooting granny style, Moon sinks the first basket. The second rebounds off and Monix tips it in right at the buzzer for two points to win.
The Spurs' coach offers Withers his position back. The now-former ABA Commissioner offers Jackie a position on the staff of the NBA Assistant Commissioner, as a marketing director. As Jackie is about to accept, the Commissioner is mauled by the Dewie the bear.
