Youth gangs took over the slums of Rio de Janiero during the 1960s and didn't relinquish their
stronghold until the mid-1980s. Only a sucker wouldn't have turned to crime and this is exactly
how naive teen Rocket views himself. Rocket shoots all of the action with his weapon of choice,
a camera.

The story's protagonist, Peter LaFleur, is a charismatic underachiever and proprietor of a rundown gym called
Average Joe's. Peter's humble gym catches the eye of White Goodman, the power-mullet-sporting, Fu-Manchu-d,
egomaniacal owner of Globo Gym, a gleaming monolith of fitness. White intends to take over Average Joe's, and
Peter's non-existent bookkeeping is making it all too easy for him. The only way Peter can save Average Joe's
is a showdown dodgeball competition against Globo Gym.
