In the first teaser video for Sharkwater: Extinction, we see Rob Stewart freediving through crystal clear waters with a school of Great Hammerhead sharks. The video is set to the hauntingly beautiful song “Child of the Water” by Chantal Kreviazuk, which was inspired by Stewart and #teamsharkwater. Sharkwater: Extinction is a follow up to Stewart's award-winning films, Sharkwater and Revolution. It’s set to hit theaters October 2018.
