Paul Aufiero (Patton Oswalt), a 35-year-old parking garage attendant from Staten Island, is the self-described world's biggest New York Giants fan. He lives at home with his mother, spending his off hours calling in to local sports-radio station where he rants in support of his beloved team, often against his mysterious on-air rival, Eagles fan Philadelphia Phil. Pauls family berates him for doing nothing with his life, but they dont understand the depth of his love of the Giants, or the responsibility his fandom carries. One night, Paul and his best friend Sal (Kevin Corrigan) spot Giants star linebacker Quantrell Bishop at a gas station in their neighborhood. They impulsively follow his limo into Manhattan, to a strip club, where they hang in the background, agog at seeing their hero. Paul cautiously decides to approach him, stepping into the rarefied air of football stardom, and things do not go as planned when he is unexpectedly beaten up by his favorite player. The fallout of this chance encounter brings Paul's world crashing down around him as his family, the team, the media and the authorities all engage in a tug of war over Paul, testing his allegiances and calling into question everything he believes in. Meanwhile, the Giants march toward a late-season showdown with the Eagles, unaware that sometimes the most brutal struggles take place far from the field of play.
