A big-screen outing for the regular cast of the popular 1970s sitcom. The Abbott family (Sid James, Diana Coupland, Robin Askwith and Sally Geeson) are in a state of permanent feud with their neighbours the Baines (Terry Scott and June Whitfield). It soon transpires that the Abbott's son and the Baines' daughter are romantically involved, so the scene is set for sneaking around in spotty boxer-shorts, food-fights and chaotic dashes to the Church.
