Cien años de perdón movie plot

A group of robbers have planned to rob a bank in Valencia. They plan to snatch as many safes as possible and escape through a tunnel connected to an abandoned subway line. Despite what it looked like on the surface, the Spanish Prime Minister's spokesman found something strange: the real target of the robbers was a specific safe - Box 314, which contained the comatose former Documents left by government official Gonzalo Soriano, involving the government's shocking secrets. However, the robbers' plan went awry and the tunnel was flooded due to torrential rain, leaving them with nowhere to run. Meanwhile, the bank's security guards were not instructed to let them escape despite the robbery following instructions from some parts of the government in power.
