Officer Angie (Mario Casas Mario Casas) is the leader of the seventh anti-drug unit, who is ordered by his superiors to lead the anti-drug team to root out the well-established local drug trafficking network. To accomplish this dangerous task, without the help of Rafal (Antonio de la Torres Antonio de la Torre), Rafal is not only a good partner of Angie, but also an experienced veteran policeman. With the cooperation of Angie and Rafal, the underworld forces are losing ground, and although not all of the means used by the anti-narcotics teams are aboveboard, they are clearly on the balance marked with "justice". At the juncture when the mission is about to be successfully completed, the appearance of a mysterious woman disrupts the pace of Rafal, who has always been mature and stable. Between suspicion and trust, the seventh narcotics group is facing an unprecedented test.
