Close to bankruptcy, ex-Lord Donald Brocklebank (Roger Lloyd-Pack- Harry Potter and the Goblet of Fire) is forced to sell the sprawling mansion he lives in with his wife and schizophrenic son James (Leo Bill - 28 Days Later). Lady Nancy Brocklebank (Kate Fahy) has taken seriously ill and Donald must now arrange for a family nurse to come and care for her.
James would like nothing more than to prove to his father that he is a responsible adult. In a misguided attempt to do so, James tragically locks Nurse Mary out of the house. As the stress of looking after an ailing patient increases, James' own mental condition worsens and his ability to care for his mother diminishes along with his ability to tell fantasy from reality in this nightmarish decent into hell.
