After getting involved in a crime, his uncle, a retired policeman, bails him out and gets him a spot to join the Provincial Police as an aspiring officer in the thick urban sprawl of Greater Buenos Aires' West Zone. Soon he will get involved in a new type of corruption.

An administrative police officer, Franco Montero, receives as an inheritance the care of a half-brother that he did not know.
