Thom, a young and brilliant engineer, is obsessed with the Bank of Spain safe, built 100 years ago, without plans and with a security system that includes an underground river that floods the room if there is a leak. When he learns that a legendary lost treasure will be deposited here for just 10 days, Thom will devise a meticulous plan alongside a charismatic art dealer to storm the bank. They will only have 90 minutes to do so, when security personnel turn their attention to the 2010 World Cup final played by Spain and the Netherlands.
