The Endless

As children, brothers Aaron and Justin Smith escaped from a secluded cult and built separate lives away from it. Years later, messages from their former “family” threaten them and demand that they return, drawing the brothers back to the group they left behind. While trying to understand why the cult wants them there, Aaron and Justin begin to suspect that its supernatural beliefs may be based on something real, and that their past is tied to a far stranger problem than they expected.
