This Shark Week special follows YouTuber Mark Rober and actor Noah Schnapp (from Stranger Things) on an epic adventure to help scientists in the Bahamas attract sharks for more in-depth studies. It's Noah's first time diving with sharks, but Mark has swam with these magnificent creatures before, and has some wild engineering tricks up his sleeve to help find the sharks.

This episode has it all - from abandoned lighthouses, to glow in the dark chum, to launching custom made chum torpedoes from actual submarines - it's nonstop shark action.
