"After an accident with the original diver, Carlo finds himself alone in a giant water tank holding a camera. A twenty-foot-long hammerhead shark is about to be lowered into the tank with him... Carlo is helping his mom film a documentary for the Danger Channel. A twelve-year-old battling a shark! It'll be a sensation! But don't worry, the hammerhead is the gentlest of sharks, and this one is old and nearly toothless, so he should be fine. But Carlo is still paralyzed with fear, and as the shark is lowered into the tank he realizes something isn't right... They sent down the WRONG shark!"
