The four officers of Unit 7 have a tough mission: eliminate the city's most dangerous drug trafficking network before the opening of the 1992 Seville World Exhibition. The film follows Angel (Mario Casas), Miguel (Joaquín Nún̈ez) the leader of the unit, and Mateo (José Manuel Poga) an aspiring detective, and Rafael (Antonio de la Torre), a violent yet effective force to be reckoned with. Failure is not an option in this compelling action thriller and the line between dedication and corruption becomes blurred as the officers struggle to gain ground in their mission.
