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 garments, where he encounters the Little Pale Girl—a mysterious entity in similar clown attire. A lone patron sees Art interacting with the girl, who is invisible to him, before being killed by Art. A year later, in 2018, teenager Sienna Shaw is preparing her Halloween costume: an angel warrior made by her father, who recently died of a brain tumor. Her younger brother Jonathan has become fixated with Art since discovering sketches of him in their father's sketchbook. That night, Sienna has a nightmare of Art and awakens to a fire on her dresser; a sword that was a gift from her father remains unscathed.
