In a post-ice age North America. After her father is killed in the fight with a fox, Judy kills it in revenge, only to be transformed into a fox herself. To change back to bunny, Judy starts a dangerous journey to the mystical mountain, accompanied by her own worst enemy, a fox cub named Nick, who shows her the true side of the foxes in a way she'd never imagined.

Foxy stared at the picture that had fallen to the ground, surprised to see himself holding a small child in his arms. He held the boy close, giving him a warm hug as the other three looked on happily. On the back was written 'Mikey, Foxy, Bonnie, Chika, Freddy... Friends Forever'. Foxy felt his heart freeze as he glanced at the guard who had tears in his eyes and recognized him.
