When a plane crossing the Serengeti desert is forced to land due to malfunction, the passengers manage to find refuge at a large satellite tracking facility. It's big and sophisticated and it's got all they need: hot and cold running water, comfy beds, and a large fence to keep the predators out. But they're about to discover that the deadliest animals are on the inside. Something from out there where the satellites roam has become trapped here, and it's turned all the staff into mutated zombies. For the eleven survivors of the plane crash, that big old fence keeping the predators out has turned their safe haven into a prison. And they're serving a death sentence.
