Free divers find love and death in Netflix's 'Deepest Breath'

Early in "The Deepest Breath," an underwater drone follows free diver Alessia Zecchini as she plunges 100 meters down into the ocean's dark depths, and back up, all on a single breath.

The heart-pounding, claustrophobic three-and-a-half-minute sequence is as difficult to watch as it is mesmerizing.
