Vampires? No Such Thing.
Aliens, though, that's something else.
They've been here, living quietly among us, since before the Industrial Revolution.
Their goal: To ensure we never leave our Solar System. We have a bad habit of wiping out indigenous populations, and theirs is the nearest inhabited planet to ours.
So when a scientist at Sydney University harnesses the power of wormholes, making interstellar travel a virtual walk in the park, one of these tall, pale-skinned aliens, Callum, is forced to choose: destroy us, or help us survive the inevitable Armageddon.
8 billion Earthlings, and our survival is in the hands of one guy - alien - meant to wipe us out.
