Milly Shapiro, the American actress who terrified audiences with her memorable role in Hereditary, is back in the horror genre.

A blend of Home Alone and post-apocalyptic horror, Hallowarrior follows a Halloween-obsessed girl who lives by herself in a cosy house filled with spooky memorabilia. But when a sinister group of scavengers turns up at her doorstep, she must fight to defend her home. Ben Sottak directs, and Shannyn Sossamon (Sinister 2) also stars.
