Knock Knock 4K UHD Blu-ray Collector's Edition Digipak

In this chilling, suspenseful thriller from acclaimed director Eli Roth — now on 4K for the first time — devoted family man Evan (Keanu Reeves) is home alone on a stormy night when two stranded, mysterious women (Ana de Armas, Lorenza Izzo) show up asking for help. Opening the door to the two young women, Evan becomes trapped and tormented inside his own home as his kind gesture leads to a sadistic, twisted game of seduction, manipulation, and temptation.
