A young possum's misguided wish for a white Wishmas not only freezes her entire hometown of Sanctuary City, but also threatens the lives of all who live there. Before the magical Wishmas Tree dies, she must undertake a perilous journey into the WILD; battling self-doubt, ghostly predators and ultimately, Extinction itself, to reverse the damage she has caused and save her city.
