Escaping from his criminal baptism, Reynaldo Galíndez lands in the patio of the house inhabited by Carlos Vargas, a retired security guard. Vargas proposes a deal: the young boy will repair the damage caused to his home when falling in return for not being handed over to the police. The lessons given to the teenager by the old guard will give rise to a relationship not unlike the old legends of educating a king. The agreement will start to fall apart when the loose ends of the robbery Reynaldo had participated in start wrapping themselves round them.
