UNIT 7 has a tough assignment: to clean the most dangerous drug trafficking networks out of the city and bring an end to the corrosive power that has taken hold of the streets. A detail of four, the unit is led by Ángel, a young officer aspiring to detective status, and Rafael, a violent, arrogant yet efficient cop. But the unit's operations are slipping outside the bounds of the law through their use of violence, coercion, lies and half-truths. For them, anything goes. As they progress with their unit operations, the two officers grow apart. Angel follows his ambition and police excesses while Rafael slowly changes due to a woman he meets.
