The film tells the story of Pola and Titina, and the avalanche of emotions that causes in them the loss of their beloved dog Cuco, who dies of old age. Accompanied by their grandmother, Pola goes across the seven stages of mourning: denial, shock, anger, grief, depression, guilt, and acceptance. After fitting the loss of Cuco in their hearts, Pola receives Plumbago from her grandmother, a pup who teaches her that everything that begins, ends, but also that everything that ends brings something new.
