Based on the juvenile delinquency of the 1970s and 80s in Spain. Set in Barrio de la Mina in Barcelona, one of the most conflict neighbourhoods in Spain. it follows real juvenile delinquents all with criminal records, used to give the film a realistic touch.

A veteran policeman named Fernando feels a lot of hatred against Ángel because the boy ran him over with a car leaving him lame. Now Fernando accuses the young crook of having participated in a robbery at a gas station in which a murder has occurred. Helped by his friends, Ángel rebuilds the facts that serve him as an alibi, but while he is in pre-trial detention in La Modelo prison (Barcelona) a terrible mutiny will take place.

While the Torete rob banks, the Heifer, another delinquent who has not noticed it, enters the same place to rob him. After failing the coup, both decide to associate.
