“Knock Knock” is a psychosexual thriller not intended for the faint of heart and easily disturbed. In the upcoming Keanu Reeves starrer, critically acclaimed horror director Eli Roth takes fear notches higher as he pits a married man Evan (Reeves) against two irresistible seductresses Genesis (Lorenza Izzo) and Bel (Ana de Armas) who initially knocked on his door for help on a rainy night eventually turning his dark fantasies into his worst nightmare and his life a living hell.
The movie comes in a world where everyone has seen everything and nothing shocks anymore, an entire generation of kids strive for attention and validation through social media, each one trying to get more likes than the next. Evan, a devoted father and husband was left alone for one weekend with nary an idea that he is being stalked by unlikely predators waiting for the perfect time and pin him down at his loneliest.
