To find a girl who disappeared under mysterious circumstances, a young priest puts his faith in a demon hunter who's known for his unorthodox methods.

A room reeking of a Type 2 demon leads the team to an underground fight club, where Nancy strikes a deal with the owner. Keta looks for Lucía's body.

Keta has history with Isaac -- and she's sure it's tied to the case. Mariana gets to know her protector, a woman who claims she can keep her safe.

A frightened Mariana runs for help, while Elvis seeks wisdom from his father. Keta learns she's much more powerful than she realized.

Elvis and his crew race to find Mamá Chabela and the children in time. Elsewhere, a spell has Isaac behaving unlike himself.

When all signs point to the end of the world, the team gathers supplies and prepares to fight back -- or die trying.
