At 35 years old, seven feet tall and 450lbs, Walter Crunk (WWE star Paul 'The Big Show' Wight) stands out at St Thomas's Orphanage. So when he almost burns the place down, the head nun hooks him up with a luckless fight promoter (Mark Feuerstein) to earn the money for repairs. As their road trip begins, Walter's not much of a fighter. But after tussles with loudmouth dads, nasty bikers and a pro-wrestling bear, he's soon the hottest act on YouTube. Big Show, big heart, big wind problem.
