After alerting the police about his wife’s disappearance, Símon hijacks a car and follows Valeria by tracking her phone but finds it abandoned. 

Meanwhile, tired of chasing her, the traffickers shoot Valeria and take her to a container at a food warehouse. There, the doctor notices that she’s alive but proceeds with the extraction of her heart after injecting her with something that makes her brain dead.

As per the cop’s instructions, Símon returns home and waits for a ransom call with his family.
