In a world devastated by a nuclear disaster 400 years ago, the privileged few found refuge in the Ark, while the outsiders mutated into beasts. Helm, a young biologist in the Ark, lives a life of indulgence…or so it would seem.

Yet his life takes a surprising turn when a captivating outsider tries to hold him hostage. Faced with a choice, Helm escapes the Ark, only to realize that the dangers outside may be more treacherous than he ever imagined…
