“Horror has a new name - The Knock Knock Man”
A group of teens dare each other to summon a mysterious figure from an old urban legend but what was suppose to be a harmless game turns deadly when one of them breaks an unspoken rule, unleashing the terrifying entity into the real world. Now hunted one by one, the friends must uncover the dark origins of the legend and find a way to banish the spirit before the knocking comes for them next.—Joseph Mazzaferro
