Last Breath is a 2019 documentary film directed by Richard da Costa and Alex Parkinson. It relates the story of a serious saturation diving accident in 2012, when diver Chris Lemons had his umbilical cable severed and became trapped around 100 metres under the sea without heat or light, and with only the small amount of breathing gas in his backup tank.
The documentary uses genuine footage and audio recorded at the time of the accident on the divers' radios and body cameras, supplemented with interviews of several of the individuals involved, as well as some reconstructed footage, to tell the story of the accident.
