In 1697, an exorcism on the young French girl Rapunzel Gothel in Germany failed. The girl was killed, but the demon continued to live in the castle of Father Petrosinus, who carried out the exorcism and sold the building shortly afterwards. Centuries later, one of the last relatives of the priest enters the castle. Alina Grimm and her friends want to shoot their final student film, a horror movie, in the castle. Unsuspecting that their presence will conjure up Rapunzel Gothel's demon again, they roam the castle to take test shots for their project. But the demon wants revenge... and if he can't have the Father, then at least a relative of the same blood.
A pair of siblings get caught up in the revenge campaign of a malicious demon who wants to kill the descendant of an exorcist.
