It is towards the end of World War II. After invading an island in the Philippines, Japanese servicemen meet fierce counter-offensive from the locals and the allied forces. It's just a matter of time before the few survivors are wiped out. Tamura (Shin'ya Tsukamoto) is abandoned by both his platoon and the mobile hospital. Traipsing through the jungle past the dead and dying, he reunites with two men from his unit who hunt for what they call "monkey meat". Weakened by hunger, illness and fatigue, Tamura looks ready to be reclassified from human to simian.
