Grown Ups
Dick and Mandy, a young working class couple, move into a council house in Canterbury, and find Mr. Butcher, one of their former teachers, living next door.  Mandy's unmarried sister, Gloria, is constantly dropping in, and will not take any hints that the couple would prefer to be left alone, until her presence finally goads them into action.  The entire film comes to a head when both couples are found wrestling in the hall while trying to oust the poor sister from the Mr. Butcher's bathroom.
