Plot
A goat named Mei wanders into a barn one night, seeking shelter from a storm. In the barn, the goat meets another refugee. The two can neither see nor smell each other, but nevertheless they huddle together, fending off the cold, and begin to talk. Eventually, they establish a friendship. The two decide to meet later and will recognize each other by using the password "one stormy night". The next day, when they meet, Mei learns that his companion from the night before was a wolf named Gabu. Despite their natural predisposition as enemies, they share a common bond and begin meeting regularly. However, Mei's flock and Gabu's pack eventually find out about their relationship and forbid the friendship. Mei and Gabu, hoping to preserve their friendship, cross a river during a storm. They hope to find an "emerald forest" free from persecution.

However, Giro, the leader of Gabu's pack, holds a grudge against goats and views Gabu as a traitor to all wolves. Giro and his pack begin to hunt down the two companions. Gabu and Mei reach the summit of a mountain where they stop and rest, exhausted from fighting their way through a snowstorm. Mei, knowing that Gabu has not eaten in days, offers to sacrifice himself as food. Gabu agrees initially, but soon realizes that no matter how hungry he is, he cannot eat his friend. Gabu hears his pack approaching and faces them, ready to defend his goat friend to the death. As Gabu is about to go face the wolf pack, there is an avalanche. The next morning, Mei digs through the snow blocking the cave and sees the "emerald forest" they had been searching for in the distance. Gabu is missing, but Mei finds him in another cave. Gabu has lost his memory of their friendship and all the events that preceded the avalanche. While waiting for the moon to come out, Gabu taunts Mei that he plans on eating him. Mei, saying that he wouldn't have minded being eaten by Gabu before, accuses the wolf of not being the Gabu he previously knew. Angrily, Mei shouts that he wishes that he had never met Gabu on "one stormy night". On hearing these words, Gabu's memory returns, and they happily reunite. In the end, Mei and Gabu both enjoy watching the moon as it rises.
