Jean-Michel Cousteau, son of legendary explorer and film director Jacques Cousteau, embarks with his children Céline e Fabien and his crew on a 3-year voyage from the Fiji Islands to the Bahamas to discover the oceans and their microfauna, a secret worldthreatened by human action. Based on rare observations that occur perhaps once a year, Cousteau guides viewers in a technically advanced diving experience to reveal that the tie between marine life and the health of our planet remains underrecognized. The film was made using 3D 4K in super slow motion in order to capture the image of small sea creatures never seen before.
