A 900-pound domesticated grizzly bear named Boog, with no survival skills, has his perfect world turned upside-down when he meets Elliot, a scrawny, fast-talking wild mule deer. When Elliot convinces Boog to desert his idyllic existence living in a garage decked out with all the comforts of home, and try the 'wild' life, things quickly spiral out of control. With open season upon them, and the hunters arriving in force, Elliot must help Boog get in touch with his inner grizzly to unite the woodland creatures and take the forest back!
