A pop balad, a love letter to cinema. The confession of a group of survivors Berta Álvarez gets the job of telling the story of Mario Ruiz, a psychiatric patient. 'An exceptional case' is what they call him, without explaining clearly what it is that makes him so. Through Mario's story and his situation in general, Berta will have to find out what secrets Mario Ruiz's family are hiding, what truth is hidden behind this love story and what happened with Louis Garrel, the object of Mario's desire. Berta must overcome her prejudices so as to be able to face up to her own past. A tale of people who manage to survive without a heart, of people who kill for love and die without knowing why. A story about genealogical, if not genetic, inheritance, and family.
