Eight masked criminals break into the building of the Spanish national mint, from where they intend to rob almost two and a half billion euros. The action from the outside is led by a mysterious Professor (Álvaro Morte), who for several months previously prepared specialists in various fields for the attack of the century. The participants of the jump do not know their names, for safety reasons they address each other using pseudonyms taken from the names of world cities. They also cannot develop a closer relationship. The professor has prepared an extremely complicated plan, it seems to take into account every eventuality and have everything buttoned up, but not everything is going as expected.
