A new trailer for supernatural horror When Evil Lurks has arrived, offering a better look at the plague of possessions terrorising the film's rural community.

When Evil Lurks follows Pedro (Ezequiel Rodríguez) and Jimmy (Demián Salomón), a pair of brothers who discover that a demonic entity is poisoning local livestock. Unfortunately, their well intentioned attempts at an exorcism go horribly wrong, unleashing an epidemic of possessions upon the community and forcing them to search for a cure.

When Evil Lurks arrives in theatres on Oct. 6, before coming to Shudder on Oct. 27.
