Jenny has devoted her life to her husband, the famous naturalist Wilkie Walker. But this year, as winter comes on, Wilkie seems distant and depressed. In desperation Jenny persuades him to visit Key West, but the sun and tropical scenery do nothing to cheer him up. As he grows even stranger, Jenny becomes involved with some intriguing local characters including Gerry, an ex-beatnik poet, and Lee, the dramatically attractive manager of a women-only guest house.

Wife, secretary, confidante, housekeeper - might Jenny at last break free from her role as Wilkie's support act?
