Somewhere within the Arctic Circle, a pregnant polar bear narrowly escapes a pack of vicious wolves only to give birth to a stillborn cub. The bear's spouse sets out to find a replacement baby bear to lift the female bear's spirits—but fails in his quest. However, he does come across a newborn human infant, which he steals from the infant's parents and takes back to his mate. As the adult bears raise the human child to be a bear, the child's birth parents desperately search for their son.
