Nacho is Marcos' older brother, with whom he has a complicated relationship. Studious and responsible, he is unable to rebel against the oppressive environment that exists at home. But deep down he also wants to fly away. For now, his priority is to go to university, while he continues to abide by the dictates of his father. The death of his mother in a traffic accident increases the rivalry between Nacho and Marcos, since both blame each other for the tragedy.

Marcos is accused of the death of his father, beaten to death with the typewriter with which he forced him to do his homework. He is a boy with no apparent problems, almost a leader, and nobody can explain what happened. Only Álvaro, his Literature teacher, will help him to accept himself and start on the road to improvement. Days before the terrible event, Marcos enjoys with his friends, Sandra and Raúl, the best moments of his life.
