May 1964. Inspector Hilario Soler is in charge of investigating the murder of Gonzalo Romeu Sotomayor, one of the most important businessmen in the construction sector of Barcelona during the developmentalism. The body has a note nailed to its forehead with a pin that reads: “For Simon”. A world full of interests, hating and passion surrounds the investigation, that will turn into something much darker as it advances, something unimaginable that transcends the present time and has its roots in the dark past of history’s protagonists.
