Scientist Dr. Riley Elliott is tracking two of the ocean's most legendary apex predators – great whites and makos – as they head on a collision course during their yearly migration off the coast of New Zealand.

Alison Towner has risked her life many times, tagging and studying great white migration patterns in South Africa for the past decade. Now she's assembling the next generation of shark explorers for a spectacular adventure.  Together, her all-female crew will pull all the stops — cage dive, free dive, drones, decoys, breeches and more — to track her missing white sharks.

Shark Week veterans Dr. Craig O'Connell and Mark Rackley dive into the great white infested waters off of Cape Cod looking to test cutting-edge shark deterrents to help keep the waters of the Cape safe for both beach-goers and sharks, before it's too late.
