The Red Lionfish is by far the coolest fish on the block: armed with eighteen venomous spines, he hunts, invisible to its prey, in packs. He has grand ambitions, too, spreading to new and unprepared waters: the Atlantic Ocean. The film sheds light on stunning abilities that let the lionfish conquer foreign waters, and by doing so threaten entire ecosystems. With stunning visual, high-speed footage, the film tells a suspenseful story, spanning over three continents and two oceans.
