The Deepest Breath plot
"One dive. One breath. One chance."
Alessia Zecchini descends with a single breath to remarkable depths beneath the sea and enters what she describes as the last silent place on earth. The Italian champion is determined to set a new world record in freediving, a dangerous extreme sport in which participants try to reach the greatest depths without using diving equipment. Participants often experience blackouts on takeoff, necessitating the help of safety divers such as Stephen Keenan, a free-spirited Irish adventurer who fell in love with the sport. Alessia and Stephen have developed a special bond and train together in this documentary to dive into a long tunnel under the Red Sea.
