Deadly Waters (Mysteries in Our National Parks)

Something's gone wrong in the Everglades. The manatees are dying, and park officials want the Landons to find out what's causing the, "Deadly Waters." It was supposed to be a fun day of fishing and picture taking for the Landon kids and 14-year old Bridger Conley. Everything changes when a stranger in a speedboat suddenly steals Jack's camera, leaving the trio face-to-face with an injured manatee and a seven foot shark.
