A wealthy, elderly man is being taken care of by an evil housekeeper who is working to be the heir to his fortune. While she navigates her plan, she is slowly poisoning him. Along comes his disowned grandson, an actor, who sees through the housekeeper's plans. He sets up a movie version of Moliere's Tartuffe, which is about a man who blindly follows a charlatan, Tartuffe, who is working to become heir to a fortune as well. The Tartuffe film is slow moving and has trouble getting around to the climax, but it's still interesting. Not Murnau's best, but worth a look.
