Álvaro and Carlos are two inmates recently arrived at a juvenile correctional facility located by the sea. While serving their sentences, they must face threats from the Los Pajaritos gang without losing hope in an increasingly dark future. But there, they also find support from inmates like Saray, a young woman who prefers to live in the facility rather than return to her troubled life on the outside, and from staff like Mario, a man who will risk his own life to help these children.
