Basharat Najib has been trying to trace his grandmother Ellen for his elderly mother Yasmin for ten years. As a young girl, Yasmin was adopted by her stepfather and grew up happily with his family in a village in Pakistan. She subsequently married a local man and returned to England with him and their children in the 1950s. Yasmin has always wanted to meet her birth mother. Basharat hasn't found her so far, but he has found two half-sisters of Yasmin's - Marguerita and Silva. They all meet in Norfolk to get to know each other more. When twins Janet and Michael's mother died, they became aware of a family secret. While their father was away fighting during the Second World War, their mum had become pregnant - and the baby girl had been given up for adoption. After years of searching, Janet and Michael had given up hope of ever finding their half-sister, Brenda, until a change in the law allowed relatives of people given up for adoption to contact them. They were finally brought together with Brenda, and now they are meeting her with a newly found letter which may give a clue as to who her father was.
