Marcela Pieldelobo, a police inspector in Pamplona, is convinced that orders can be discussed, that there are things that need to be kept for oneself and that closed doors can no longer be closed if you know how to open them. Even if you don't have a warrant. Now the past, in the form of an abuser father reappearing after his mother's death, knocks furiously at his door, and Marcela decides to concentrate in the case of a baby abandoned in a solitary parking lot and a car with no trace of the driver, but with blood and footprints... When the tracks lead to a company owned by one of the most traditional and influential local families, her superiors decide to take it away from the case... But Marcela insists on going ahead.
