Úrsula (Ana Polvorosa) is a mother and experiences two tragedies simultaneously, a zombie invasion and the fact that her husband has left home and has taken Nicolás, her son. Obviously, for Úrsula, the zombie invasion is "an anecdote", for her as a mother and as a woman the only thing that worries her is her missing and defenseless son in the face of a world infected by green, unbalanced and murderous beings.
