Peter LaFleur is a charismatic underachiever and proprietor of a rundown gym called Average Joe's. The facility's ecclectic clientele of decidedly less-than-average Joes is comprised of: a self-styled pirate; a scrawny nerd who dreams of impressing an unattainable cheerleader; an obsessive aficionado of obscure sports; a dim-witted young man; and a cocky know-it-all who, of course, really knows nothing. 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.
