Veteran bear trainer Jeff Watson takes on perhaps his toughest task in more than 25 years of rescuing and raising the majestic animals. His goal - to reverse the cycle of man's ownership over animals - involves 700-pound grizzlies Bob and Screech, whom he has raised since they were 6 weeks old. Now, after three years, Jeff believes their destiny is to live in the wild, and `Project Grizzly' tracks the trainer's emotional struggle to undo all he has taught the bears in captivity. At a remote Indiana location, Bob and Screech must learn how to hunt, fish and hibernate, and ultimately break their dependence on a human. Unforeseen hurdles lead to some doubt, but Jeff is determined to complete this incredible, dangerous challenge.
