Kellingley Colliery in North Yorkshire is the last deep coal mine in Britain, and this film follows the miners working underground in the months before it shuts for good. Cameras go down into the pit alongside men who have spent decades cutting coal in the dark, some of them following fathers and grandfathers into the same seams. Interviews with the miners and their families trace what the closure means beyond a lost paycheck: a way of life, a community identity, and a trade with a history stretching back generations in the region. The film sets Kellingley's end against the longer arc of British coal, once the engine of the national economy and the backbone of towns like this one, now reduced to a single working pit before even that goes dark. Rather than treating the closure as an abstract policy story, it stays close to the men on the shift floor, letting their own account of the work and its ending carry the film.
