In the prison infirmary, Fede Cortés remembers the roller coaster ride of his life. Prime suspect for multiple murders, he tells a story, written according to the conventions of noir, that plunges us into a delirious atmosphere where the line between good and evil is blurred and happiness, a scarce and finite resource, is distributed as arbitrarily as justice. "If I feel happy, my neighbour will have had an agonising toothache. That's how life works".
