Ahead of its World Premiere at SXSW later this month, the Nicolas Cage-starring dystopian horror Arcadian has unveiled its first official trailer.

In a near future and after a catastrophic event depopulates the world, normal life on Earth is no more. Paul and his two sons, Thomas and Joseph, have been living a half-life – tranquillity by day and torment by night. Every night, after the sun sets, they face the unrelenting attacks of a mysterious and violent evil. One day, when Thomas doesn’t return home before sundown, Paul must leave the safety of their fortified farm to find him. A nightmarish battle ensues that forces the family to execute a desperate plan to survive.

As Nicolas Cage’s character explains of the creatures in the trailer’s voiceover, “There are those who believe they came after the pollution people caused, and they’re here to cleanse the planet of the human race so we’ll all become extinct.” The trailer only grants us a peek at the monsters in question, but they sure look like they can pack a punch.

Jaeden Martell (It, Knives Out), Maxwell Jenkins (Lost in Space) and Sadie Soverall (Fate: The Winx Saga) star opposite Cage. Ben Brewer directs the film from a script by Mike Nilon.

Arcadian will release in cinemas from April 12th. Watch the trailer below:
