Paul Aufiero (Patton Oswalt), a 35-year-old parking-garage attendant from working-class Staten Island, is the self-described "world's biggest New York Giants fan." One night Paul and his best friend, Sal (Kevin Corrigan), spot star Giants linebacker Quantrell Bishop at a gas station in Staten Island. They impulsively follow his SUV into Manhattan to a strip club, where they finally muster up the courage to talk to their hero.
What starts out as a dream come true turns into a nightmare as a misunderstanding ignites a violent confrontation, and Paul is sent down a path that will test his devotion to the extreme.
