A gruesome wartime discovery leads a Spanish police detective-turned-soldier on the hunt for a cunning serial killer in this thriller from veteran director Gerardo Herrero (The Invisible Woman, Turn to Black). When a regiment of the Spanish 'Blue Division' stumbles onto the frozen corpses of a Cavalry Squadron, the fact that one of the dead soldiers had his throat slit with the message "'Watch out, God is Watching You" scrawled on his shoulder leads to an investigation headed by Arturo Andrade, a soldier whose background as a police inspector makes him the ideal man for the job. Along with the perceptive Sergeant Estrada, Andrade begins the arduous process of attempting to root out a ruthless killer in the midst of a cruel war.
