This thrilling series is the best of every shark story you’ve ever experienced. From terrifying encounters and incredible feats, to gang warfare and alien invasions, each episode is a wall-to-wall shark invasion. Footage from actual attacks, shark interactions or bizarre behavior (both professional and user-generated) kicks off each mystery. Our investigation then takes us to new attacks, new footage, and the deeper we dig, the more we uncover. By the end, what started as one mystery becomes multiple events that lead to a single stunning revelation.
