Can a film change the way people look at the ocean? Can we explain the greatest natural mystery of our planet? Can we help our children believe in a better and more sustainable world tomorrow? This is the triple challenge of Yann Arthus-Bertrand’s new cinema adventure that highlights the scientific missions of TARA expeditions, a unique pool of international researchers, oceanographers and biologists. Through astonishing photography, the film takes us on a magnificent journey into the heart of the least-known regions of our planet. Filmed in extreme geographical conditions all over the globe, the film follows the modern odyssey of people who go out to discover their blue planet. Directed by Yann Arthus-Bertrand and Michael Pitiot. Produced by Hope Productions.
