Three adult siblings show that behind the veneer of middle-class Sussex life, what you see is not always what you get. When their recently widowed mother, Vivien, falls in love with a new man, Mark, and introduces him to Jake, Natalie and Helen, they greet him with a mix of excitement, optimism and outrage. Each of the siblings has their own personal problems, and when they become suspicious that Mark could be after their inheritance, tensions rise and relationships within the family become challenged.
