A group of robbers planned to rob a bank in Valencia. They plan to grab as many safes as possible and then escape through the tunnel connected to the railway line under the wasteland. Despite the appearance, a spokesman for the Spanish prime minister found something strange: the real target of the robbers was a specific safe deposit box, box 314, which contained documents left by Gonzalo Soriano, a former government official who was in a coma, involving the government's biggest secrets. However, the robbers made an unexpected mistake in their plan. The tunnel was inundated by the heavy rain and they had nowhere to escape. At the same time, although the robbery was carried out in accordance with instructions issued by some departments of the government in power, the bank security guards were not instructed to let them escape.
