When a devoted husband and father is left home alone for the weekend, two stranded young women unexpectedly knock on his door for help. What starts out as a kind gesture results in a dangerous seduction and a deadly game of cat and mouse.
Unfortunately the movie Knock Knock is not yet available on HBO Max.
