The military anti-terrorist army takes control of "Chuspi", an unknown and faraway small village, isolated by the terrorist group "Sendero Luminoso" (Shining Path). A soldier called Vitin Luna, and other young soldiers face an invisible, perhaps superior force. Their unit is commanded by a brutal lieutenant who declares the entire village guilty of treason. In the face of this crisis, Vitin must choose between blind obedience and his own conscience.

Passion, criminal instincts and traditions melt together in this film that shakes our understanding of crime.
