We’re used to seeing hordes of the undead in zombie films and TV shows — but it turns out that just one can be a big, big problem.

In the new horror film It Stains the Sands Red, Brittany Allen plays a woman named Molly, who is stranded alone in the desert after a zombie apocalypse and finds herself being pursued by a lone ghoul, who, unlike her, has no need to stop and rest.

It Stains the Sands Red is directed by Colin Minihan and written by the Vicious Brothers, a.k.a. Minihan and Stuart Ortiz. The film will receive its world premiere at the upcoming Sitges Film Festival in Spain, which begins Oct. 7. See an exclusive clip above.
