Eaten by Jaws and Big Wave Surfing| Edge of the Unknown on Disney+

JUSTINE DUPONT (VOICEOVER): [SPEAKING FRENCH]

FRED DAVID: Four years ago, we moved to Nazaré. And we decided to focus on big wave surfing. Every big wave is different. But I think Nazaré is probably the best place to learn how to deal with big waves.

MAN: For me, surfing big waves is totally terrifying. So much of the training is about how to survive, how not to die. You have to have an incredibly strong mind and body to face off with these 50 or 60 or 70 foot waves. When the lip of the wave crashes, it can feel like a ton of bricks smashing you into concrete. That's the impact zone. Once you're trapped there, it's nearly impossible to get out. You have to find your way to the surface between the waves and get a jet ski driver to pick you up.

FRED DAVID (VOICEOVER): Our work is really dangerous. My goal is first to have Justine safe, second, to find the best way for her.

FRED DAVID: In Nazaré, she was surfing, like, every swell every day, all day long. And she never fell. So when we got the call for Hawaii for the [INAUDIBLE] contest, she was, like, super confident. She was, OK, I'm ready.
