Alena and Tyler Worthy - the SOS Aquatic Intervention team is using new technology to save endangered dugongs in the Persian Gulf. When they get a new Red Alert, they find themselves flying half way around the world to Florida's land of Ten Thousand Islands to save manatees. A frightening, dangerous poacher named Billy Boat is stripping Florida of one of its most valuable resources: its beautiful, and exotic orchids - and making tens of thousands of dollars selling them on the black market. As his convoy of jet boats roars through the islands, they are hitting and killing manatees. The SOS team joins up with The Mermaid Squad - a group dedicated to helping manatees. But Billy Boat has other plans. The SOS team will need every bit of courage, technology, and guile to end the poaching and save the gentle creatures.
