When brothers Pedro and Jimi discover that a demonic infection has been festering in a nearby farmhouse, they attempt to evict the victim from their land. Failing to adhere to the proper rites of exorcism, their reckless actions inadvertently trigger an epidemic of possessions across their rural community.

A hard-hitting horror film whose surface-level frights are just as engaging as its thematic concerns, When Evil Lurks marks a viscerally unsettling addition to the possession horror canon.

When Evil Lurks holds nothing back in its mission to unsettle the viewer -- and it mostly succeeds, even if it starts stronger than it finishes.
