Apartment concierge Cesar (Luis Tosar) is a miserable person who believes he was born without the ability to be happy. As a result, he decides his mission is to make life hell for everyone around him. A majority of the tenants are easy to agitate, but Clara (Marta Etura) proves to be harder than the most. So Cesar goes to creepy extremes to make this young woman mentally break down. Things get even more complicated in this twisted relationship when her boyfriend, Marcos (Alberto San Juan), shows up.

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.
