A married couple, Andrew and Adrian, invite a group of friends over to their house in the country for a few days. The guests consist of two couples: Adrian's cousin Leopold, a stuffy academic, and his fiancé Ariel and Andrew's friend Maxwell, a doctor and serial womaniser, and his nurse Dulcy. Andrew and Ariel have a history - Andrew thinks of Ariel as The One That Got Away - and meeting her again rekindles those emotions. However, Maxwell is soon smitten by Ariel too.—grantss
