Hilarity and pandemonium break out when three long-married couples – respected pillars of society – discover that the parson who married them was not authorised to do so... meaning they have been living in sin for 25 years. Three Yorkshire couples, old friends and all married on the same day, gather to celebrate their silver anniversary. When they discover they are not legally married, each couple initially reacts with proper Victorian horror – what will the neighbours think? – and all three couples find themselves re-evaluating their marriages. Hovering over these dramatic revelations is the local paper’s drunken photographer, keen to record the evening's events for posterity, and a wickedly destructive housekeeper hoping to use the couples' embarrassment to her own advantage. A timeless classic comedy masterpiece by JB Priestley.
