Net wanneer de straten veilig leken, duikt een seriemoordenaar met een fetisj voor hoofdhuid op. Frank is de teruggetrokken eigenaar van een mannequinwinkel, maar zijn leven verandert wanneer de jonge kunstenares Anna hem vraagt om haar met haar nieuwe tentoonstelling te helpen. Als tussen beiden een vriendschap ontstaat en Franks obsessie escaleert, wordt het duidelijk dat ze een lang onderdrukte drang tot stalking en moord heeft aangewakkerd.
Nee, helaas is Maniac nog niet beschikbaar op Netflix in Nederland.
