There's a terrifying new doll on the horror scene, and her name is Jenny Pen.

Arrogant Judge Stefan Mortensen (Rush) suffers a near-fatal stroke, leaving him partially paralyzed and confined to a retirement home. Resistant to the staff and distant from his friendly roommate, Mortensen soon clashes with seemingly gentle resident Dave Crealy (Lithgow) who secretly terrorizes the home with a sadistic game called "The Rule of Jenny Pen” while wielding his dementia doll as an instrument of cruelty.
