In the final ten episodes of this terrifying series from the visionary minds of Guillermo Del Toro, Carlton Cuse, and Chuck Hogan, nuclear winter envelops the planet, and a desperate, weakened humanity, existing only as slave labor for 'The Partnership,' is controlled by the bloodthirsty strigoi. Meanwhile, the sinister 'Master' grooms Eph's son Zach to rule the post-apocalyptic dystopia.
