Isolde passes her life inside a strange but fascinating castle, as far from the city of Medellin, in which it is located, as are its inhabitants and the life they live. The sense of unreality in which they live is oppressive for the teenager, who finds in the forest surrounding the castle the only possible respite from her loneliness. But the invisible menace of the outside world filters silently through the branches. With pitch perfect suspense, Jorge Franco constructs a sinister fairy tale that transforms into the crazy story of a kidnapping. Inside and outside the fortress, love, that indomitable monster, becomes an obsession that distances and dehumanises, that attempts to overpower, that awakens the desire for revenge, and can only be escaped by accepting death as one's fate.
