When brothers Pedro (Ezequiel Rodríguez) and Jimmy (Demián Salomón) discover that a demonic infection has been festering in a nearby farmhouse — its very proximity poisoning the local livestock — 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. Now they must outrun an encroaching evil as it corrupts and mutilates everyone it is exposed to, and enlist the aid of a wizened “cleaner,” who holds the only tools that can stop this supernatural plague.
