I recently saw Room (Original novel and screenplay by Emma Donoghue) which follows the story of a mother and son (Jack, aged 5) trapped in a room by a male abductor.
The story is told from the perspective of the 5 year old who was born there and has never been in the outside world. He has lived within the confines of the four walls his entire life. His only relationship is with his mother, who gives her undivided attention; cooks cleans and cares for him. He makes sense of the outside world through 2 or 3 TV channels , which to him, is an imaginary world – ‘magic TV land’.
