Omar Mumba has a unique hobby: collecting letters. They are letters from non-profit associations that operate in those lands where people's needs are absolute. Omar always reads them, even when he is on duty in the hotel where he works. For this reason he is mocked by colleagues and superiors. The attitude of helping others makes him alone. His days pass between listening to U2's music and housework, work and a recurring accusation: who punctures the tires of his boss' car?
