Terrifier

A facially disfigured woman who survived a massacre the year before is interviewed for a TV talk show. Once off air, the host, Monica Brown, makes cruel comments to her boyfriend about the woman's appearance, only for the woman to burst out of hiding and mutilate her.
On Halloween night of 2017, two friends, Tara and Dawn, drunkenly leave a party and encounter Art the Clown, who follows them to a pizzeria. Art is kicked out by the restaurant's owner for smearing his feces over the bathroom walls. The girls discover that Dawn's car tire has been slashed, and Tara calls her sister Victoria to pick them up. Art returns to the pizzeria and kills the owner and a worker.
While waiting, Tara asks a pest control worker, Mike, to be let into the apartment building he is working in to use the restroom. There, she encounters the Cat Lady, a deluded squatter who believes the doll she carries is her infant child. Art attacks Dawn and subdues Tara with a sedative.
Tara awakens, bound to a chair, to see Dawn suspended upside-down. Art forces her to watch as he saws Dawn in half. Tara escapes but Art shoots her to death, then attacks Mike. The Cat Lady discovers Art with her doll, and in a plea for the return of her "child", attempts to show motherly compassion by cradling him.
Victoria arrives and discovers Art, who has mutilated the Cat Lady and is wearing her scalp and breasts. Art chases her and decapitates Mike's co-worker Will. Victoria then finds Tara's corpse as Art attacks her with a makeshift cat o' nine tails. Mike knocks Art unconscious. The two flee and call 911 but Art recovers and kills Mike, then hits Victoria with a pick-up truck. As Victoria lies unconscious, Art begins to maul her face. The police finally arrive, but Art shoots himself before he can be apprehended.
After the police discover Victoria is still alive, Art's body and those of his victims are taken to a morgue, where Art reanimates and attacks the medical examiner. One year later, Victoria is released from the hospital after rehabilitation; she is revealed to be the disfigured woman from the film's opening; thus the events of the film showed the massacre that took place the previous year.
