Toni, a high school teacher angry with the world, decides to end his life. Meticulous and serene, he has chosen the date: a year from now. Until then every night he will write, in the apartment he shares with his dog From him Pepaand a library from which he gradually becomes detached, a personal chronicle, hard and incredulous, but no less tender and humorous. With it, she hopes to discover the reasons for his radical decision, to reveal every last particle of his privacy, to recount his past and the many daily affairs of a politically troubled Spain. His parents, a brother he can't stand, his ex-wife Amalia, from whom he can't disconnect, and his problematic son Nikita will appear, dissected with a relentless scalpel; but also his caustic friend Patachula. And an unexpected Águeda. And in the succession of loving and family episodes of this addictive human constellation, Toni, a disoriented man determined to recount his ruins, paradoxically infuses an unforgettable life lesson.
