Boog, Elliot, and their forest friends return with an all-new adventure, this time in a Big Top Circus! The comedy begins when Boog's pals choose their family obligations over the annual guy's trip, and a disappointed Boog decides to take a trip of his own, which leads him right into the middle of a circus ring...literally. When he switches places with a devious look-a-like circus grizzly and falls for an alluring Russian troupe member, he'll come to realize that maybe you don't have to choose between family and friendship after all.

After falling head over hooves in love with Giselle, Elliot's road to the altar takes a slight detour when Mr. Weenie is kidnapped by a group of pampered pets determined to return him to his owners.
