The Great Hammerhead Stakeout follows shark scientist Dr. Tristan Guttridge and former Royal Marines commando James Glancy as they carry out an audacious plan to stake out the barrier reef of Andros Island in the Bahamas. They’re hoping to find out whether local fisherman’s reports of big sharks choosing Andros’s waters as home are true, and to do this they are using a revolutionary underwater tent, tethered to the seabed. The tent is a base for operations, allowing the two divers to stay underwater for ten hours non-stop and to carry out different dives out of the tent to the drop-off, the channel system, and the shallow flats of the interior. As the plan unfolds Tristan and James have multiple encounters with sharks including a Tiger Shark and several Great Hammerheads. The film conclusion is that Andros itself, a wild and undeveloped environment makes the perfect home for these big sharks and perhaps this abundant natural sanctuary is causing Great Hammerheads to stay put and enjoy this rare environment.
