In September 2012, the young Mr. Lemons was trying to repair some pipeline along the floor of the North Sea when disaster struck on the surface 300 feet above, ultimately severing the “umbilical cord” that connected the diver to his ship and stranded him in the pitch-black deep with only seven minutes’ worth of oxygen in his reserve tank.

Alex Parkinson's true-life adventure thriller, based on his 2019 documentary, recounts the efforts to rescue a saturation diver trapped hundreds of feet below the water's surface.
