In the tranquil town of Timberline, a 900-pound grizzly bear named Boog has his perfect world turned upside down after he meets Elliot, a one-antlered mule deer.

But little do they know, Bob and Bobbie have left a trail of dog treats in the forest for Mr. Weenie to follow, which he does and he ends up getting taken back to his original home by his owners.

Boog wakes up early in his cave one spring morning and prepares for a guy's trip to start spending more time with his male friends.

A few months after the events of the first film, Elliot tells a campfire story about the legend of the Wailing Wampus Werewolf that is said to live in the Timberline National Forest one night.

At Dead Bear Gulch, Elliot and Mr. Weenie are both caught by the werewolf, who is actually Shaw in a costume; fortunately, Boog and his friends leap to the rescue.

"[1] A short film titled Boog and Elliot's Midnight Bun Run is featured on the Open Season DVD and Blu-ray.
