The Knock Knock Man

A group of teenagers challenge each other to summon a legendary, eerie figure from an urban myth. What begins as a simple, playful dare quickly spirals into a nightmare when one of them disregards a crucial unspoken rule, unleashing a sinister entity into the real world. As the friends are stalked and picked off one by one, they must dig into the dark history behind the legend and discover a way to banish the malevolent spirit before it comes for them next. — Joseph Mazzaferro
