This is the miraculous true story of a deep sea diver's rescue, when his lifeline snaps during a maintenance dive. The film is based on the documentary of the same name that chronicled the actual rescue.
200,00 cables crisscross the ocean floor These cables periodically need repair and the divers that do the work consider it to be one of the most dangerous jobs one can have. This particular story is about three divers in the North Sea, who are plunged into darkness when a topside computer glitch causes havoc with their ship's systems. While all three start out 300 feet down in a diving bell, one of them becomes separated and is quickly running out of air. The entire film is based on the rescue attempt.
The three divers are played by Woody Harrelson, who stays in the diving bell feeding the lifelines to divers David Yuasa, played by Simu Liu and diver Chris Lemons, played by Finn Cole. It is Mr. Lemons who becomes cut off from the other two and is in the most peril. The film also co-stars Cliff Curtis and Mark Bonnar.
There are many very tense moments and actual footage from the documentary are cut into the film providing real context. It's a quick 90 minute film but it will probably have you holding your own breath for the last 45 minutes..
