After so long at sea with Dolpin Universe, Jody is as mad about dolphins as ever! Now the McGraths have arrived at the Marquesas Islands, along with the rest of the Dolphin Crew. Jody's mum and dad are keen to check out some wild Spinner dolphins - known to be shy with humans - and Jody's hoping she'll get to see some, too. But the spinners are under threat from local fishermen in the area. The fishing nets are trapping the dolphins and endangering their lives. Soon Jody has another rescue on her hands, when some adventurous spinners fight for their lives in the nets . . .
