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 Guinea, 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.
As Killian matures, he learns about the history of his family's land and the struggles they faced during the colonial era. He also discovers that his father's legacy is threatened by the arrival of foreign investors who want to take control of the cacao industry. Killian must decide whether to fight for his family's future or to embrace change and adapt to new circumstances.
Throughout his time in Fernando Poo, Killian faces many challenges, including political unrest and economic hardship. He must navigate these obstacles while also maintaining relationships with his family and community. He also encounters love and heartbreak, as he falls in love with a local woman named Maria and experiences the pain of losing her to illness.
Despite these challenges, Killian remains committed to his family's legacy and strives to protect their land from destruction. As the independence movement gains momentum, Killian joins forces with other members of the community to fight for their rights and freedom.
In the end, Killian emerges as a hero and leader in Fernando Poo, having grown both physically and emotionally as a result of his experience there. He returns to Huesca with a newfound sense of purpose and a deeper understanding of the world around him.
