The Deepest Breath, the new documentary feature from Irish director Laura McGann, which tells the story of the Italian freediver Alessia Zecchini and the Irish expert safety diver Stephen Keenan, is released next month - here's a look at the trailer.
The synopsis for The Deepest Breath reads: "Champion freediver Alessia Zecchini fell in love with the sport as a child growing up in Italy, astounding coaches with her raw talent and determination in pool swims and open water contests before she was even old enough to legally compete.
"Irish adventurer turned expert safety diver Stephen Keenan, meanwhile, was raised near the sea, but as a young man he set out on a quest to find himself, traveling across Africa before landing in Dahab, Egypt and establishing a dive school.
"Despite their very different paths, the two would meet at the pinnacle of the competitive freediving world, discovering a shared passion for pushing their limits and forming a powerful relationship that felt like fate.
"From director Laura McGann, this thrilling documentary takes a look inside one of the most dangerous sports in the world, using everything from raw underwater dive footage to childhood home movies to chronicle Zecchini and Keenan's lives and careers.
"The bond between them propels the film's emotional journey into the stunning, silent depths of the ocean, a breathtaking place unseen by all but the fortunate few – where exhilarating accomplishments and unavoidable risks await."
Dublin company Motive Films is among the producers on The Deepest Breath.
The film opens in selected Irish cinemas on Friday 14 July and premieres globally on Netflix on Wednesday 19 July.
