When the girl Clara is kidnapped from the daycare, her mother Sylvia goes to the police station to report the missing child.
The chief inspector interrogates Sylvia and learns that her husband Bernardo is an enforcer in a bus company.
The low-middle class couple does not have any possessions; therefore they do not believe their daughter has been abducted for money.
Then he interrogates the owner of the daycare that explains that she received a phone call from Sylvia telling to deliver Clara to a neighbor that the girl knew very well.
When Bernardo arrives, he accuses the twenty-two year-old Rosa of kidnapping his daughter.
He discloses to the Chief Inspector that Rosa and he had had a love affair and the police detectives bring Rosa to the station to be interrogated and she tells that a woman forced her to kidnap the girl.
As long as the interrogation goes on, it is disclosed a dark story of betrayal, jealousy and revenge.
