Summary

From 1996 until today, 33 violent murders are perpetrated during the Halloween period in Belgium by a serial killer who calls himself "the clown". We are on the eve of Halloween. Vincent hates this party and for good reason: his father committed suicide during this period. That morning, he receives a call from his friend Alice to babysit her cats because she has to be away for a few days. On the way, he realizes that he is being chased by a strange, masked man. Very quickly, he realizes that this stranger covered in a clown mask is prowling around Alice's place, determined to enter.
