Peter LaFleur is a charismatic underachiever and the proprietor of a rundown gym called Average Joe's. The facility's ecclectic cleintele is decidedly less-than-your-average Joes. Peter's humble gym catches the eye of White Goodman, the egomaniacal owner of Globo Gym. White places a foreclosing attorney inside the Average Joe's establishment to finalize his takeover of the gym, but attorney Kate is won over by Peter's boyish charm and joins the Average Joe's team. The only way to save the Average Joe's gym is to win a showdown dodgeball competition against Globo Gym, but can his ragtag team win?
