Raising twin teen boys is a harrowing enough proposition, but when you have to raise twin teen boys in the middle of an end-of-the-world scenario, it’s even more fraught with peril. And sibling rivalry, and raging hormones, and dammit-dad-leave-me-alone-I’m-brooding. In this exact predicament is where Nicolas Cage’s Paul finds himself in Arcadian. Not only does he have to protect his sons, Joseph (Jaeden Martell, It, Midnight Special) and Thomas (Maxwell Jenkins, Lost in Space), from monsters that come in the darkness, he has to keep them from killing each other. No minor feat.
