Arrogant judge Stefan Mortensen suffers a near-fatal stroke that leaves him partially paralyzed and ends up in a nursing home. At odds with the staff and estranged from his friendly roommate, Mortensen soon encounters the seemingly meek resident Dave Creeley, who is secretly terrorizing the house with a sadistic game called The Jenny Penn Rule, using his dementia doll as an instrument of cruelty. What begins as childish torture quickly escalates into much more sinister and disturbing incidents. When Mortensen's pleas to the staff go unanswered, he takes it upon himself to put an end to Creeley's terror.
