Three teams of researchers return to one of the last hunting grounds for Air Jaws. They will use decoys, drones, and underwater cameras to count the number of breaches and collect data on hunting techniques to see if the shark population is rebounding.

Legendary boxer and entrepreneur Mike Tyson is taking on a new challenge… and he picked the most unlikely training partner. Iron Mike will go head-to-head with some of the ocean's top apex predators including the blacktip reef shark. With famed ring announcer Michael Buffer calling the shots, these two heavyweights will square off underwater, where Mike Tyson will try to score a TKO over the massive shark… all in the name of research. And don’t worry, no sharks were harmed (or bitten) in the making of this episode.
