Jack lives with his Ma in Room, a secured single-room outbuilding containing a small kitchen, a basic bathroom, a wardrobe, a bed, and a TV set. Because it is all he has ever known, Jack believes that only Room and the things it contains (including himself and Ma) are "real." Ma, unwilling to disappoint Jack with a life she cannot give him, allows Jack to believe that the rest of the world exists only on television. Ma tries her best to keep Jack healthy and happy via both physical and mental exercises, keeping a healthy diet, limiting TV-watching time, and strict body and oral hygiene. The only other person Jack has ever seen is "Old Nick," who visits Room at night while Jack sleeps hidden in a wardrobe. Old Nick brings them food and necessities. Jack is unaware that Old Nick kidnapped Ma when she was 19 years old and has kept her imprisoned for the past seven years. Old Nick regularly rapes Ma; Jack is the product of one such sexual assault.
