An ancient evil is going to be born into the world unless two dummy brothers can stop it (spoiler: they cannot). The movie is torn between needing to explain itself so we know the stakes, and wanting to withhold information for suspense. So we’re told there are seven rules to follow (that’s more than twice the number of rules for Gremlins so you know it’s serious) but one rule remains secret until the end. And since there are set rules for demon possession, and specialists with suitcases of equipment, and the local cops and government have procedures in place, we know this has all happened before, elsewhere, so if this particular demon gets loose it’s probably not the end of the world, just maybe of this town. But despite all this knowledge and procedure, the dummies keep losing ground, because (per Matt Lynch) “everyone in this forgets what’s happening to them every three to five minutes.”

Still it’s a good gruesome, apocalyptic time at the movies, and the actors are game for its grievous head injury theater.

Two attempts to shoot evil with a gun:

This is Argentina so of course somebody was in La Flor – that’s lead brother Ezequiel Rodríguez, a go-to demonic horror guy lately between Legions and The Witch Game. Brother Demián Salomón is right there with him, starring in Satanic Hispanics, Welcome to Hell, and Into the Abyss. Somebody needs to look into the current wave of Argentine horror. These guys discover the neighbor’s tenant’s kid has become demon-bloated so they drive it some hours away so it can become someone else’s problem. Too late: it gets to the neighbor, and to Ezequiel’s wife (who kills one of her kids) and dog (who kills another). The brothers drive off with the remaining (possessed, autistic) kid and their mom, pick up a demon hunter, and head to the Village of the Damned where they’d dumped the body. The spooky kids there defeat the exorcism plot pretty easily, barely even moving around much, a new evil is born, and the autistic kid eats his grandma.
