A routine deep sea diving mission in the North Sea goes terribly wrong when a young diver is stranded some 300 feet below the surface in the new film “Last Breath.”

Alex Parkinson's film is about a saturation diving accident that took place in 2012. In its journalistic way the film takes you down and lifts you up.

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.
