Synopsis

Around the Crozet Islands, here is the incredible odyssey of a family of Sperm Whales facing rapid changes in their environment. From the stormy surface to the eternal darkness of the abyss, several generations of these deep-sea divers encounter men and their "toys": harpoons of yesterday, and fishing lines of today. Once victim of whale hunting, now accused of stealing fish, a sperm whale shares its private life with us.
