Terrifier 2

After being resurrected by an unknown entity following the Miles County Massacre,[a] Art the Clown brutally murders the coroner examining his body and goes to the laundromat to clean his blood-soaked suit, where he encounters the Little Pale Girl—a mysterious entity in similar clown attire.
One year later, teenager Sienna Shaw is preparing her Halloween costume: a Valkyrie character designed by her recently deceased father. Her younger brother Jonathan has become fixated with Art since discovering art of him in their father's sketchbook. That night, Sienna has a nightmare about a commercial for "The Clown Cafe" in which Art appears. He kills various Clown Cafe patrons as Sienna tries to pull a sword from a box of cereal. She wakes from the dream in her bedroom, where a fire is burning the dresser the sword is resting on, but the sword is unscathed.
That day, Jonathan sees Art and the Little Pale Girl at school playing with a dead opossum and is blamed when his principal discovers the carcass. Sienna has a panic attack when her friends Allie and Brooke discuss Victoria Heyes's mutilation of talk show host Monica Brown.[a] Sienna and Allie go to the costume shop, where they encounter Art. Art kills the shop vendor before arriving at Allie's home trick or treating. Allie ridicules him because she thinks he’s too old to go trick or treating. Art later breaks into Allie's home and brutally maims her, keeping her flayed body alive long enough to traumatize her mother, whom he later kills.
Jonathan shows Sienna and their mother Barbara their father's sketchbook, filled with newspaper clippings revealing that the Little Pale Girl bears resemblance to Art's first victim Emily Crane. He believes their father knew how to stop Art, saying that he gifted her the sword for that purpose. Sienna departs for a Halloween party; Jonathan flees after Barbara slaps him. She is then shot and killed by Art, and when Jonathan returns home, Art kidnaps him and steals Sienna's sword.
At the Halloween party, Brooke spikes Sienna's drink; Sienna has a panic attack after seeing the Little Pale Girl in the crowd. Brooke's boyfriend Jeff drives them home when Sienna is lured to The Terrifier attraction at the old abandoned carnival. The Little Pale Girl mimics Jonathan's voice over the phone, pleading for a ride home, while Sienna goes searching alone. After a big argument on the way, Art castrates and murders Jeff. Brooke is chased into the park and murdered as well, while Sienna is beaten unconscious.
Sienna awakens to find Art using a scalpel on her brother and begins attacking him with his own weapons. The siblings discover Art is immortal and he wears them out with his endurance. He stabs Sienna with her father's sword and throws her into a portal to hell where she encounters the "Clown Cafe" again. Sienna dies but is resurrected by the sword. She decapitates Art while he is biting into Jonathan's calves. The Little Pale Girl takes his head and leaves as Sienna and Jonathan embrace.
In a mid-credits scene, Victoria (now institutionalized) writes "Vicky + Art" and obscenities on the wall with her own blood. She gives birth to Art's living head as her eyes glow bright.
