In 1953, Kilian leaves the snow-capped mountains and, together with his brother Jacobo, travels to an unknown land, distant and exotic, to the island of Fernando Po. In the depths of the lush and seductive island, his father, a longtime employee of the Sampaca estate, where the best cocoa in the world is grown, awaits him. In the eternally green, warm and voluptuous colony, life is easy, in contrast to the ossified and gray Spain; brothers work together to grow perfect cocoa from the Sampaca estate; notice the differences and similarities between the culture of the local population and the colonialists; learn the meaning of friendship, passion, love and hate. But one of them will cross the forbidden line. In 2003, Clarence, the daughter of one brother and the niece of another, decides to discover the secret of her origins, delving into the destructive past of Kilian and Jacobo and dusting off their secret.
