Carlos and Álvaro are two new arrivals at a juvenile detention center located by the sea. While serving their sentences, they must face threats from a gang called Los Pajaritos and try to hold on to hope for a future that seems increasingly bleak. But inside, they’ll also find support from fellow inmates like Saray—a young woman who prefers life in the center over returning to her troubled life on the outside—and staff members like Mario, a man deeply committed to the rehabilitation of the youths, who will risk his own life to help these kids.
