Bill, unwilling to change his sugary eating habits after collapsing from a blood sugar spike, is diagnosed with diabetes. When his first attempt to put it under control fails, a mean-spirited doctor tells him that he is going to lose his legs. After deciding to use a wheelchair (which he really does not need), he is befriended by a rugby player named Thunder, who teaches him how to be independent, but their friendship is strained when Thunder realizes Bill is not really disabled.
