In Muscletown, if you're not a jock, you're a nobody. You're an INDOOR KID. Air-ball Arnie couldn't be worse at sports. As much as he wishes he could score three-pointers or hit home runs, the fact is that he's way better at video games than he is on the court or the field. What's worse is he lives in Muscletown, a city full of the best athletes and jocks, especially the Brohemians, the town's star athletes AND the town's biggest bullies. The Brohemians get to decide the winners from the losers, and they've decided Arnie is the biggest loser of them all. But all that changes when Arnie discovers a magical medal that gives him superhuman sports powers. Now he can slam dunk better than anyone, and he's determined to put these super sports abilities to good use by putting the Brohemian bullies in their place. But when his newfound powers start to get him the popularity and admiration he's always craved, will he use his powers for good or will he strike out and foul on his own friends?
