A documentary about National Geographic Fellow Enric Sala and National Geographic Explorer-in-Residence Sylvia Earle's Ocean Now expedition to Costa Rica's Cocos Island and nearby Las Gemelas seamounts. People come to Isla del Coco in search of buried treasure, but the real riches are the abundant sea life beneath the ocean waves. Secret coves where hammerheads school in enormous numbers. Rocks and corals that ripple with color by day but at night turn into killing grounds for packs of whitetip sharks. Pristine waters brimming with missile-sized tuna and acrobatic dolphins in hot pursuit of gleaming clouds of fish. Cocos Island, a tiny dot in the middle of the Pacific Ocean more than 300 miles off the coast of Costa Rica, is home to one of the greatest concentrations of predators on the planet.
