Great white sharks have found a new home off the shores of Nova Scotia, Canada. With the waters now frothing with great whites, interactions with humans are on the rise. A team of scientists tracks down and tags the biggest sharks to uncover the sharkiest locations before there's a fatal attack.

Shark attack survivor Paul de Gelder attempts the unthinkable – getting attacked by a shark, again. Under the supervision of experts, Paul provokes sharks to attack him in multiple scenarios, where they bite and tear off prosthetic limbs to teach life-saving tactics for surviving an encounter with nature's deadliest predators.

When Shark Tagger Keith Poe saw the shark for the first time, he knew it was different. It was aggressive, 13-feet long and had very dark skin. Now, a group of experts lure the beast up from the abyss to determine if the creature is a mako, or mutant, or possibly, a mako and great white hybrid.
