Dr. Owen (Jonathan Mellor), an official from the Ministry of Health, and a Grupo Especial de Operaciones (GEO) team equipped with helmet-mounted video cameras are sent into a quarantined apartment building to control the situation. After encountering some of the infected, Owen uses religious mantra and rosary to fight them off. It turns out that Owen is actually a priest sent by the church to get a blood sample from the Medeiros girl and aid the other priest in charge of her. When they get to the penthouse, they find out that the infected can travel all around the building through the air ducts. The Medeiros girl is nowhere to be found. Larra (Ariel Casas), one of the GEO officers goes into the air duct and finds a sample of her blood the only one that the original priest took from her. Owen then performs a religious rite, and the blood spontaneously combusts, confirming that it is the blood he's looking for; however, the rest of the blood also sets on fire and Larra drops it, rendering it useless. They must then get a blood sample from the Medeiros girl herself.
