The vessel's dynamic positioning system, supplied by Kongsberg Maritime, failed. Ĭhris Lemons, along with his colleagues Duncan Allcock and David Yuasa, were carrying out repairs 100 metres (330 ft) below the surface of the North Sea, supported by the support vessel Bibby Topaz. 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. 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 (330 ft) under the sea without heat or light, and with only the small amount of breathing gas in his backup tank.


Last Breath is a 2019 documentary film directed by Richard da Costa and Alex Parkinson.
