An Improper Comedy / 3m, 3f / Interior Set / Anyone nutty enough to buy an old lighthouse for a summer home is looking for trouble. It comes on the double to a novelist, her estranged TV film star husband and the latest gleam in his roving eye when this unsociable triangle, along with the novelist's globetrotting journalist mother, a baffled editor and a grocery boy find themselves trapped on the top floor during the off season. Suspense spirals and comedy crackles during three days of confinement.
