It's 1974, and a world of unrest, power cuts, and beer at fourteen pence a pint. Joe and Russ are a couple of working class young men in the North of England, stuck in a rut of going-nowhere jobs punctuated by Saturdays drinking until they fall down at the local Mecca. But news filters through of something happening across in Wigan where The Casino, a huge pre-war dancehall, is drawing people by the hundreds for the Saturday all-night soul dances. Lured by the prospect of great music, illicit chemicals and, for Joe, the chance to get closer to the divine Jane, the lads decide to give the place a whirl.
