Heavy snow seals the village, and villagers face a food shortage crisis. Hunter Xing San overcomes hardships to bring back game, and the village chief tries to use past favor to demand he share it for free. Xing San firmly rejects emotional pressure, establishing the rule of 'silver and goods cleared,' allowing villagers willing to buy at market price to exchange for life-saving rations. Subsequently, villager Er Gou is driven by greed, ignoring deep mountain warning signs, and attempts to find Xing San's game in the mountains, only to misstep into a beast trap in Lao Xiong Gou, getting trapped in the blizzard. Faced with the accusations and pleas for help from family members and the village chief, Xing San remains unmoved, sticking to the harsh survival rule of equivalent exchange.
