In 1957, renowned wildlife artist Robert Bateman and spirited biologist Bristol Foster set out on a global expedition in a rugged Land Rover they call “The Grizzly Torque”. Starting in the UK, their travels take them to the far corners of the earth. From the lush rainforests of the Congo to the vibrant landscapes of India, Bob paints the wonders they encounter, while Bristol films on his 16mm Bolex camera. Fifty-seven years later, the abandoned Grizzly Torque is rediscovered. As its hidden history emerges and a new owner restores it to its former glory, the tale of their environmental activism through art and science unfolds.
