Filmmaker Helena de Llanos, who lives in the chaotic house, full of memories and treasures, where her grandfather, Fernando Fernán Gómez (1921-2007), legendary writer, actor and director; and his wife, the actress and writer Emma Cohen (1946-2016), shared their lives, analyzes the relationship that the living have with the dead through the places and objects they have left behind.

They are on their way and Eva is still insecure. Her deep love and devotion for Jaime has led her to accept a special offer: swinging in order to arouse their marriage after fifteen years. Jaime seems doubly confident: a curvy 19-year-old Brazilian is waiting for him, while Eva has to resign herself to an uninspiring and unattractive partner. What looked like a night of playing, liberation and revitalization for this husband and wife becomes a mess inside four walls when Jaime discovers that their partners for the evening are not who they said they were.

A photograph, a toy locomotive, and a newspaper clipping are the starting point for this story, born from a child's fascination with the true identity of Auke Bert Pattist. This child, now an adult, struggles with old newspapers, legal evidence, and suspicions that blur the reconstruction of the Nazi who enchanted his childhood. Through witnesses, unpublished documents, and locations, we delve into the figure of a Waffen SS lieutenant who came to Spain and integrated easily. Little by little, we discover a peculiar, polyglot character with a gift for people, well-known in certain circles, who, unlike his fugitive compatriots, never went into hiding despite having endured several extradition attempts. Few knew, or didn't want to know, about Pattist's dark past, when he was known as "The Executioner of Drenthe" for acts he never repented of.
