Judge Stefan Mortensen suffers a near-fatal stroke, leaving him partially paralyzed and confined to a retirement home. There, Mortensen clashes with a seemingly gentle resident named Dave Crealy, who is actually secretly terrorizing the home with a sadistic game called "The Rule of Jenny Pen" while wielding his dementia doll as an instrument of cruelty. When Mortensen’s pleas to the staff go unanswered, he takes it upon himself to put an end to Crealy's reign of terror.
