There are two completely unrelated wolves living in Canada's Emerald National Park. Kate (voiced by Hayden Panettiere) is the daughter of the leader of the western wolf pack. For her, principles, duties and responsibilities are more important than anything else; Humphrey (voiced by Justin Long) is from another wolf pack. He is always laughing and carefree. He is a hedonist. Kate is about to marry Gus (voiced by Chris Carmack), the son of the leader of the eastern wolf pack, not for love, but to prevent a terrible war that is about to break out between the two wolf packs. Things are unpredictable. On the wedding day, Kate and Humphrey were captured by the forest ranger and sent to the "Sawtooth" National Park in Idaho. In order to avoid unnecessary war between the groups, the two escaped. Can they rush back before the war breaks out and resolve the conflict? This film was nominated for the 83rd Academy Award for Best Animated Feature.
