The Rule of Jenny Pen [Mediabook 4K UHD & Blu-ray]

Dave is a cold-blooded psychopath. He gleefully panics his roommates with the help of his hand puppet Jenny Pen. He bullies, abuses, and humiliates them before finally driving them to their deaths. When Stefan moves in, Dave thinks he has an easy time with him too. But the former judge is nowhere near as defenseless as his paralyzed body suggests. A nerve-wracking psychological war breaks out between the two, which quickly escalates and turns the nursing home into a kind of hell all its own.
