Art is an aspiring Broadway dancer, struggling to live up to the expectations set for him by family and friends who viewed him as a child prodigy. Deep in the middle of a slump, things are made worse when he ends up in a car accident that injures him, albeit temporarily. Also involved in the accident was a young boy who, while otherwise uninjured, appears to have lost his memory. Feeling responsible for the boy's condition, Art takes him in, but it soon becomes clear that the boy (named "Jimmy" by Art) is not normal. Jimmy can move objects around with his mind, frequently involuntarily, and his presence sometimes causes people to see strange apparitions.
