A beaver couple live by their dam, as the seasons go by. They have babies, gather food, and maintain their dam, play and swim--and, of course, defend their territory against predators and intruders. After one of their young gets lost in the forest, the mother and father beaver search frantically for him, while he is rescued by an unlikely ally. The film features real animals--and uses new techniques to provide stunning and original never-before-seen images.
