It's been 23 years since seriously obese Georgie Godwin (Timothy Spall) left his house. His only relationship with life outside is found in daytime telly, the view from his living room window and his visitors. He relies on Janice, his kindly neighbour who comes in each day to look after him and his friend and agent Morris Morrissey (Bobby Ball). In charge of making sure he retains his title and cashes in on his size by feeding him up, Morris brings taxi loads of tourists to gawp at the "eighth wonder of the world". Then, striking up a friendship with a troubled teenager sent from Social Services to tend to his overgrown garden, Georgie seems persuaded to try to lose weight. As Morris begins to fear losing his cash cow, salvation appears by way of the local news - a chance to take on his rival Big Brian in a live weigh-in... So, what does Georgie really want, the glory of being the Fattest Man in Britain, or a life he never dreamed he could have?
