It’s 40ish minutes of pure suspense and anxiety as the story shuffles between the man at the bottom of the ocean, Chris Lemons (Finn Cole), his fellow saturation divers (Woody Harrelson as Duncan and Simu Liu as Dave) in the diving bell below the waters who are unable to help and the crew in the support vessel above (including Cliff Cutris and Mark Bonnar) scrambling to get their systems back online and operational as the clock rapidly runs out.

"Last Breath" delivers every incident with such specificity that it's like a cinematic piece of journalism. Yet it leaves you with a minor tingle of the uncanny.

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.
