Below Zero

It's a winter night, and the cold bites into a remote road in the middle of nowhere. An armored police van makes its way down it carrying several inmates being transferred from the Soria prison to the one in Cuenca. Behind the wheel is Martín, a police officer tasked with driving the vehicle and guarding the prisoners. However, the van is ambushed by a man looking for one of the inmates, and he is willing to go to any lengths. Martín manages to barricade himself in the armored compartment with the prisoners, and from that moment on, his job is no longer driving but becoming the only barrier between the inmates and those hunting them.
