A crew of advanced aliens - named the Erlitii - crash land on an unchartered planet. Unbeknownst to them, they find themselves on Earth after the zombie apocalypse is in full swing. Their initial encounter with the “native” species of this foreign planet is not even close to the peaceful meeting that they had hoped for, and now these aliens and the surviving humans of Earth must deal with this new threat. These new zombies - or Cravers - are faster, smarter, stronger, and hungrier than anything they have encountered before.
