Peter La Fleur (Vince Vaughn) is a charismatic underachiever and proprietor of a rundown gym called Average Joes. The facilitys 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 (Ben Stiller), the power-mullet-sporting, Fu Manchu'd, egomaniacal owner of Globo Gym, a gleaming monolith of fitness. White intends to take over Average Joes, and Peters non existent bookkeeping is making it all too easy for him. A foreclosing bank has stationed attorney Kate Veatch (Christine Taylor) inside Average Joes to finalize Globos takeover of the gym. But Peter's boyish charms win her over and Kate joins his team of social rejects to beat the odds and their own ineptitude to try to save Average Joes. How? A showdown dodgeball competition against Globo Gym.
