Jack Wilde and his friends are on holidays at Hazard River when they discover a dead shark washed up on the sand. It has no fins. Is it the work of a monster shark ... a giant squid ... or pirates? The gang decides to investigate. But finding out what killed the shark lands the kids in a whole lot of trouble.
