The Mouth of the Wolf (Spanish: La boca del lobo) is a 1988 Peruvian drama film directed by Francisco José Lombardi[1] that is based on the Socos massacre.

The story follows Vitin Luna (Toño Vega), who is attempting to make his ways up the ranks and enter officer school, his companion Kike Gallardo (José Tejada) and other troops must face the Communist guerrilla group Shining Path during the internal conflict in Peru, an invisible army that devastated the area and is seemingly superior.

The troops are sent from the coastal metropolis of Lima and are racist towards the impoverished Andean peasants in the town due to cultural differences, seemingly arriving in a foreign land.

Later that night, Kike and another soldier interrupt a celebration of a marriage proposal in the town, with the two being attacked while attempting to forcibly enter the event and being accused of raping Julia.

When the troops return to their garrison, the imprisoned Luna mocks the hypocrisy of Roca calling him a coward, with the two playing Russian roulette down to the final chamber.
