Down on his luck after losing his job and his girlfriend on the same day, Larry decides to join his neighbour, Bill, and his combat-happy buddy, Everett, for a relaxing weekend of drinking and target practice. But when the three hapless guys are mistaken for Army Reservists they're loaded onto an army plane headed for Fallujah, Iraq and mistakenly ejected in a Humvee somewhere over Mexico. Convinced they're actually in the Middle East, the clueless wannabe soldiers lay down their beers and take up their arms to save a rural village and prove they just might be heroes after all.
