Rose invites them to stay at an estate now owned by her husband, Tony. Belinda confesses that she never liked Rose and had a fling with Tony years ago, but beggars can''t be choosers. But the increasingly awkward visit turns deadly, when a member of the household is found murdered and all clues point to Belinda.
