In 2015, Mick Fanning became a legend around the world when he walked away unharmed after a terrifying encounter with a shark. It was caught live on camera as the world-champion surfer prepared for a wave at a surfing event in South Africa.

Since retiring from professional surfing, Mick has gone on a journey to come to peace with that experience and to find out more about these apex predators. It's the focus of a new documentary, Save This Shark.
