Knock Knock, directed by Eli Roth and released on October 9, 2015, is a psychological horror-thriller that explores themes of temptation, guilt, and the consequences of our choices. With a screenplay co-written by Roth, Guillermo Amoedo, and Nicolás López, the film stars Keanu Reeves, Lorenza Izzo, and Ana de Armas in a story that takes viewers on a suspenseful and unsettling journey.

At its core, Knock Knock revolves around the character of Evan Webber, portrayed by Keanu Reeves, a successful architect who appears to have it all: a beautiful home, a loving family, and a flourishing career. However, when his wife and children leave for a weekend getaway, Evan finds himself alone and vulnerable. This sense of solitude sets the stage for the film’s exploration of temptation and the dark side of human desire.

The film takes a sharp turn when two young women, Genesis and Bel, played by Lorenza Izzo and Ana de Armas, unexpectedly arrive at Evan’s doorstep during a rainstorm. Initially, their arrival seems innocent; they are lost and seeking shelter. Evan, portrayed as a well-intentioned man, takes them in, displaying a mix of hospitality and curiosity. This moment marks the beginning of a tension-filled narrative that rapidly escalates from innocent flirtation to a harrowing nightmare.
