Despite their initial reservations, Yogi and Boo Boo take the bear cubs into their home and take care of them. Meanwhile, Jellystone Park has gone over budget and the park commissioner orders Ranger Smith to close it down. This means that Yogi, along with the other bears at the park, must be sent to a zoo.

Together they make their escape from the park to find a new home.
