When an unspeakable evil takes over the world, the only protection for a mother and her twin sons is their house and strong bond. Needing to stay connected at all times -- even tethering themselves with ropes -- they must cling to one another and never let go. However, when one of the boys questions if the evil is real, the ties that bind them together are severed, triggering a terrifying fight for survival. Starrin Halle Berry
