In the new, Toronto International Film Festival-screened horror movie Hellions, Chloe Rose plays a pregnant 17-year-old who decides to stay indoors on Halloween. The problem? Well, that would be pint-sized demons who want her unborn baby.

Directed by Bruce McDonald — who made 2008’s terrific zombie movie, Pontypool Hellions costars Robert Patrick and is released in theaters, on VOD, and digitally on Sept. 18.
