Every summer Rita moves into a converted cowshed and lets out her Welsh farmhouse to holiday-makers. However, her last visitors trashed the place and left it in such an appalling state that her mother never recovered from the shock. Bent on an unusual form of revenge, she tracks the family down to their latest summer destination - a fisherman's cottage in Cornwall - and persuades local caretaker, Reg, to give her a hand.
