Chacabuco is the story of Claudia (Malena Villa), a teenager who, due to force majeure, must return to live with her father Marcelo (Pablo Flores Maini) for a summer after fifteen years of living apart. The stay takes place at his grandfather’s house, who died recently, where he spent all his family vacations. The arrival at the house of Pipo (Camilo Cuello Vitale), Claudia and Sara’s boyfriend (Lala Mendía), the grandfather’s caretaker, will help the union of the central bond, interweaving it with a journey through the sexual awakening in adolescence, and a journey through memory, where the past plays a fundamental role for understanding and reconciliation with the present.
