Out of shape, bored to death, and stuck in small town nowhere (without a car), Cain's life is bland; the voice in his head that (critically) narrates every move he makes isn't helping matters.
Then a film crew comes to town, and everything changes overnight. A second voice in Cain's head starts speaking after years of silence, and Cain is pulled into a world filled with superhuman cops, mad scientists, and anti-augmentation activists.
This is Cain's new world. A world of more.
