This documentary records the journey undertaken by Jacques Cousteau, his 24-member team, and an NFB film crew to explore the Grand Banks of Newfoundland, one of the world's richest fishing areas. They discover shipwrecks, film icebergs and observe beluga whales, humpback whales and harp seals. The film also includes a fascinating sequence showing Calypso divers freeing a calf whale entrapped in a fishing net.
