Welcome to Alaska in the fleeting summertime, when the biggest gang of grizzlies on the planet gathers to gorge on salmon and to mate. The explosive action plunges you into the rough life of survival-defending your fishing spot with tooth and claw, and doing whatever you must to find a fertile partner. Beware: it's not always pretty. Powerful players can have their way. But life is harder for a new mother and her cubs, and for young males who risk their lives to rival bigger, older bears. The dedicated film crew takes risks, too, using the latest HD cameras and hi-tech remotes to put you right in the heart of the sometimes steamy action.
