There's a storm brewing at the Women's Rural Institute in Prior's Ford. When WI president Moira Melrose is defeated in an election by village newcomer Alma Parr, the two neighbours are soon caught up in a bitter dispute - and are dragging the entire village into battle with them. At Tarbethill Farm, Bert McNair refuses to forgive his son Victor for selling some of their farmland to developers and things take a dramatic turn that no one could have predicted... When poison-pen letters appear on the doormats of the villagers, the residents are forced to face some of their darkest secrets. But just who wrote the letters? And what do they have to gain by causing so much scandal?
