The reporter Angela Vidal (Manuela Velasco) and her cameraman Pablo (Pablo Rosso) shoot an episode for the television documentary "While You're Sleeping" in Barcelona. They accompany a group of firefighters to a rescue operation in an apartment building in the city center. When they arrive there, they find a woman covered in blood, who bits a police officer. But when they wanted to take their injured colleague out of the building, the building was completely sealed off by the Spanish health authority and no one could get in or out. Nobody knew what was happening there until an official of the health organization came in with protective clothing to take blood samples from everyone present and to care for the injured. Suddenly the injured officials, who were in the next room, turns into aggressive and bloodthirsty beings and started to attack the bystanders. The official explains that this is an infection that makes people extremely aggressive and is transmitted by saliva. He also reports that this unknown infection was discovered in a dog at a veterinary clinic that attacked all other animals in the clinic. The dog was then anesthetized and put to sleep but could be traced back to this housing development via a chip in the ear, whereupon the health authority placed it in quarantine. The situation escalates and the struggle for survival begins.
