A young lady is about to hang her new antique mirror to the wall when someone mysteriously leaves a box on her doorstep. As she gets ready to open it, knocks start to spread around in her apartment. Who is it? Or should we say what is it?
Unfortunately the movie Knock Knock! is not yet available on Paramount Plus.
