Enrique Urbizu's thriller La Caja 507 (Box 507) is about two very different men looking for the same thing. Modesto (Antonio Resines) is a banker who loses his daughter Maria (Dafne Fernandez) when she dies after being trapped in a forest fire. After a robbery at the bank in which papers from Box 507 are taken, Modesto discovers documents that reveal the fire was set on purpose. With his wife Angela (Miriam Montilla) in a coma thanks to the robbery, Modesto sets out to even the score. Gangster's henchman Rafael (Jose Coronado), who needs the stolen papers to get back on his boss' good side, is also looking for them. The two men meet in the end when all is revealed.
