For centuries, great whites were believed to simply stalk their prey. Now, groundbreaking science believes that these alpha sharks are highly intelligent predators that adapt their hunting techniques in real time. For the first time on Shark Week, the full range of great white hunting tactics will be revealed, reinforcing their status as one of the ocean's top predator.

After a wave of mauled marine life washes ashore in New York, conservation biologist Dr. Craig O'Connell launches an investigation to find the culprit. When it leads to an old nuclear dumping ground teaming with great whites and makos, he is left with the chilling theory that the predator may be radioactive. A deeper dive reveals an unexpected hotspot for massive makos off the coast of the Hamptons, suggesting that these waters may be hiding something even bigger beneath the surface.

How far will people go to fuel their fascination with sharks? For four devoted shark "fin-atics," their obsession shapes every aspect of their lives. From a dentist who spends every spare moment searching for life-size shark replicas that overwhelm his home to a woman who insists she has a special connection with her shark "boyfriend," and a world-record holder covered in shark tattoos, this special explores how their daily routines, relationships, and finances revolve entirely around the apex predators they can't live without.
