Arrogant judge Stefan Mortensen suffers a near-fatal stroke that leaves him partially paralyzed and ends up in a nursing home. Resentful of the staff and estranged from his friendly roommate, Mortensen soon encounters the gentle-looking resident Dave Crealy, who secretly terrorizes the home with a sadistic game called “The Rule of Jenny Pen.” when he uses his dementia doll as a tool of cruelty. What begins as childish torment quickly escalates into much darker and more disturbing incidents. When Mortensen’s pleas to the staff go unanswered, he takes it upon himself to put an end to Crealy’s reign of terror.
