18世紀末，日本東北。在一個天寒地凍而食物短缺的村莊裡，堅強的Rin承受村民的歧視，努力過生活，她靈魂的救贖就是山，而早池峰山被認為是盜賊女神居住的地方。某天，Rin的父親Ihei由於無法忍受饑餓而偷竊，為了保護父親，Rin自告奮勇離開村莊，將自己放逐山林。Rin越過了被告知永遠不能跨越的山神廟，深入山中。她在逃離追趕她的狼群時，碰到了一個被視為傳說中人物的「山野男人」。
Late 18th century, Tohoku. In a village suffering from food shortages due to cold weather, Rin lives a strong life despite being looked down upon by the people. Her soul's salvation was Mt. Hayachine, where the goddess of thieves is said to dwell. One day, Rin's father, Ihei, who could not bear her hunger, committed theft. In order to protect her home, Rin voluntarily leaves the village to protect her father who is being blamed by the villagers. Rin crosses the mountain god's shrine, which she is told never to cross, and heads deep into the mountain. As Rin runs away from her wolves, what appears in front of her is a "mountain man" who is feared as a legendary being.
