Watch the incredible odyssey of sperm whales facing rapid changes in their environment.
From the surface shaken by dreadful storms to the gloomy abyss, several generations of sperm whales encounter humans and their weapons: yesterday whalers' harpoons, today fishing lines. We discover in turn their mysterious sonars, their enemies the killer whales but also the strange world of their neighbours, the monsters of the abyss.
It has taken more than 7 years to complete this extraordinary documentary which maintains the myths of terror and fascination inspired by the oceans.
