A new ocean phenomenon known as The Blob sends juvenile great white sharks straight into a feeding frenzy of monster 20-foot adults off Guadalupe Island. A team of shark experts dives deep to discover if the young sharks survive or become a snack.

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.
