On the sunny and seemingly ordinary Friday of January 13, 2006, the bohemian martial-arts instructor Fernando Araujo and his hand-picked four-member crew storm into the branch of Banco Río in the affluent neighbourhood of Acassuso, Buenos Aires. As the thieves work fast, emptying dozens of safety deposit boxes crammed with millions of dollars, precious jewelry, and heavy gold bullion bars, the chief negotiator Miguel Sileo and his armed men encircle the silent two-storey building in the aftermath of the Villa Ramallo robbery. Five determined bank thieves and twenty-three helpless hostages find themselves trapped inside the building, and the question is whether the audacious robbers will get away with the heist of the century.
