For Unit 7, there is no thin line separating unethical resources from those that are openly illegal. His modus operandi: violence, coercion, lies, and half truths...anything goes. Unit 7 consists of: Ángel (Mario Casas), a young aspiring inspector, intelligent and compassionate, Rafael (Antonio de la Torre) an expedient police, forceful and arrogant, Miguel (José Manuel Poga) and Mateo (Joaquin Núñez) The socarrones of the Group and capable of the greatest brutalities, but also of unexpected signs of tenderness. Between Angel and Raphael a strange understanding will emerge and they will end up resembling each other more than they ever imagined.
