With oil actively gushing into the Gulf’s waters, National Geographic Explorer and wildlife expert Mireya Mayor, together with adventure underwater cameraman Andy Casagrande, join the extensive mission to save struggling creatures at the center of the crisis. Dive into the sludgy mess across the Gulf region with Mireya and Andy as they work to rescue pelicans, sea turtles, dolphins and many other creatures that use the Gulf as a migration superhighway. Along the way, they investigate the science behind the toxins and the anticipated impact they will have on coastal life for years to come. From the marshlands of Louisiana to the beaches and coral reefs of Florida - the beloved home state of both Mireya and Andy - watch their race to protect the injured creatures from an uncertain future, and follow their investigation after the oil spill was ultimately contained.
