A person who longs for revenge can become a murderer. In the joint investigation of a criminal case with Commissioner Fernando de Vega, the private individual Diego Lesemann comes to this realization. This time, along the stormy Costa Verde, the green coast of northern Spain, there are three victims. Diego Lesemann travels to Asturias in the picturesque autumn to attend the wedding of the daughter of a former school friend. During a walk along the cliffs, he discovers the body of a young pregnant woman who bears a striking resemblance to his friend's daughter. Commissioner de Vega begins the investigation and asks his friend Diego Lesemann for support, drawing him once again into a complex criminal case.
