In 2004, Spanish military doctors Pablo and Diego are on a humanitarian mission in Iraq. After a terrorist attack on the road, Pablo and Diego seek refugee in a house in a small village. Pablo is forced to kill a teenager and his father in self-defense and he faints, seriously wounded. He awakens in a hospital in Spain and soon goes home with amnesia to be with his wife Ángela and daughter Pilar. A man called Baza seeks Pablo out and gives a contract of confidentiality for him to sign; in return, he and his family would be financially supported by the Spanish Army. However Pablo blames himself for the death of the Iraqi teenager and his father and wants to remember what happened. He meets Diego and finds the truth about the incident. What will be his attitude?
