The beaver, once almost exterminated, finds a home and safety in Canada's national parks. He also discovers that man can be his friend. Grey Owl, the famous naturalist, had a special talent for making friends with the beaver. Scenes show the beaver coming Grey Owl calls, climbing into his canoe, accepting food. Wrestling is the beaver's favourite sport, and one of Grey Owl's friends becomes so fearless that it even enjoys wrestling with a human being.
