Ben Stone is terrified. He's terrified because he weighs 601 pounds and needs his right leg amputating. He's terrified because a crane will shortly lift him from his fourth-floor flat and lower him 44 feet to an ambulance waiting below. He's terrified because he hasn't been outside in nine years and he doesn't know who will look after his beautiful dog.
He needn't worry though, because the world is about to end.
