Polyester (1981)

Blessed with a keen sense of smell and cursed with a philandering pornographer husband, a parasitic mother, and a pair of delinquent children, the long-suffering Francine Fishpaw turns to the bottle as her life falls apart -- until deliverance appears in the form of a hunk named Todd Tomorrow. Originally screened with "Odorama" scratch and sniff cards so the audience could (at their own risk) smell along with the film.
