Chirin is an innocent though adventurous young lamb whose carefree life on the farm comes to an abrupt end when a wolf murders his mother. Confused and angry, Chirin pursues the wolf into the mountains, seeking revenge. The laws of nature are brutal, however, and hatred alone won't be enough to avenge the loss of his mother. Only the strong survive in the wild, and obtaining that strength may change Chirin forever.
