 Monica, a London landlady, gets a new lodger, Gerald, an American financial consultant, who s recently divorced his wife. And a mysterious woman who seems very much at home in Gerald s room. But it s not what Monica thinks...and as she gets to know "Geraldine" better, she begins to learn more about herself, too. But when Gerald gets arrested in a dress, and he s fired, it s up to Geraldine (and Monica) to vindicate him and get back his self-respect.
