In it we travel to Barcelona in 1981, specifically to May 23 of that year. Exactly three months have passed since the attempted coup d'état in the Congress of Deputies and the population is barely recovering from the shock.

With more than 200 hostages in the bank, the robbers soon reveal a hidden objective that has nothing to do with obtaining financial loot.
