Killian is a young man who has never left the remote mountains of Huesca (Spain) which saw him grow up. In 1953, he travels back to the exotic Equatorial African island of Fernando Poo, in Spanish Guinee, where he was born, to work in a cacao plantation alongside his father and his brother. During 20 years in this island, until the troubled days of independence, he will undertake a journey towards maturity and knowledge, but will also have to deal with pain and loss.
