Jean-Michel Cousteau, son of ocean pioneer Jacques Cousteau, offers a breakthrough look at a secret world within the ocean that is perhaps the biggest story of all—that the smallest life in the sea is the mightiest force on which we all depend.  Alongside marine biologist Holly Lohuis, he invites viewers to dive into this whole new world that will leave them in awe of the beauty and diversity of the oceans – the source of all life on our planet – and inspire an even stronger desire to protect what they have either seen for the first time or perhaps re-discovered along the journey.
