In Shizuoka Prefecture, amidst the mountains along the Tenryu River, there lives a man known as "The Legendary Trap Hunter." 70-year-old Katagiri Kunio patrols those mountains, reading the movements of wild animals and setting snare traps in order to catch boars and deer. As a pioneer of trap hunting, he's led the field for over 40 years. What's more, he considers it his duty to personally subdue the prey he catches and bring it in alive, ensuring every last bit of meat is recycled without the slightest waste. In the tranquil forest, we record the heated battles of a man who lives alongside nature.
