Set in Montreal during the disco era, the film revolves around the Starlight, a fictionalized version of Montreal's famed Lime Light discothèque. It depicts this world starting in 1976, when Montreal was considered one of the world's top nightclub destinations, through to 1980, when the fashion for disco was about to experience a sharp decline. By the early 1980s political issues such as Quebec's 1980 independence referendum had fractured and polarized the city, and Montreal had also begun to experience a decade of economic decline. By then, it had ceased to be the largest city in Canada, and had ceased as well to be Canada's financial and industrial centre.
