An exploration of the sensory experience of the TauTona gold mine in South Africa, showing migrant labourers working in dark, claustrophobic environments and the ear-splitting noise of drilling. The TauTona mine in South Africa, known as 'Western Deep' is the world's deepest gold mine. Employing more than 5,000 people, it operates twenty-four hours day. The film begins in complete darkness as the miners descend three-and-a-half kilometres underground. McQueen documents an intense work regime where the temperature can reach over ninety degrees celsius. Accompanied by jarring sounds created by the mechanical equipment, Western Deep is a hellish representation of labour that makes the silent resolve of the miners all the more powerful.
