La boca del lobo Colonna sonora (1988) OST

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.
