In a morgue, Art the Clown resurrects and brutally murders the coroner examining his body before going 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 pulls a sword from a box of cereal. She wakes from the dream and finds her dresser on fire, but the sword resting on it is unscathed.
Later 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 goes to a costume shop where Art antagonizes her. Art kills the shop clerk when she leaves and arrives at Allie's home pretending to trick or treat. He later breaks into her house and brutally maims her before killing her mother.
Jonathan shows Sienna their father's sketchbook, filled with sketches of Art and newspaper clippings of 10 year old Emily Crane who was murdered. He believes their father knew how to stop Art, saying that he gifted her the sword for that purpose but their mother Barbara scolds Johnathan for his fixation on Art. Sienna departs for a Halloween party while Jonathan runs away after Barbara slaps him. Barbara is then shot and killed by Art and when Jonathan returns home, Art kidnaps him and steals Sienna's sword.

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.
