A 900-pound grizzly bear named Boog living in the town of Timberline (Martin Lawrence) meets Elliot (Ashton Kutcher), a one-horned mule deer. They end up stranded together in the woods during hunting season and they have to beat the hunters with the help of all the other animals. In the end, Boog decides to stay in the forest and says goodbye to his owner Ranger Beth (Debra Messing).
