Seeing the fish he loves to catch disappear 15 year old Jack Nixon enlists ocean conservationist Sylvia Earle in what becomes a years long quest to save a dying ocean. Explorers Brian Skerry, Captain Max Kennedy and a band of teenage aquanauts bolster expeditions to the high-seas killing fields of the industrial fleets to the rapidly melting polar ice of the Chukchi Sea. Harvard biologist Dr. E.O. Wilson, deep diving pioneer, Dr. Richard Pyle, and Stanford’s Dr. Barbara Block inform the mission. Apollo 8 astronaut Major General William Anders and activist Bill McKibben provide lessons of how humanity met past challenges. Sobered by a close examination of the daunting scale of the challenge, the teenagers find hope in nature’s ability to heal and the ways a previous generation overcame the global test of World War II.
