A bank. A safe box. An information that would shake a country.

A group of thieves led by a man called El Uruguayo stalk a bank in Valencia to steal as many safety boxes as possible and later flee through a dug tunnel that communicates the building with an abandoned subway station. However, the press officer of the Prime Minister discovers what the thieves are actually after: they want to get their hands on box 314, property of Gonzalo Soriano, a former member of the government who slipped into a coma after a severe accident, left documents with compromising information. The gang's plans start to go awry when the tunnel is flooded by heavy rain, leaving them with no escape, plus to discover that the box really doesn't contains documents, but an external hard drive full of data about important names in all levels of the Spanish politic. At the same time, a fixer of the government receives the mission to assume the control of the negotiations, looking for recover at any cost the box 314 and the information before the robbers flee with it.—Chockys
