399 Forever is a documentary that follows passionate wildlife guides and photographers who have dedicated their lives to tracking, teaching, and protecting Grizzly 399, the world's most famous bear. As they capture her story, they also confront the growing impact of social media on wildlife, work to educate the public, and fight for practical solutions like bear proof trash cans to keep both bears and people safe. With mounting pressure to remove grizzlies from the endangered species list, the film explores the heart of a complex and emotional debate: what does it really mean to protect a wild animal?
