This revealing documentary explores the world of polygamous marriages among British Muslims. While polygamy is illegal under British law, it is permitted under Sharia law, and while it's unusual, some estimate that there are as many as 20,000 polygamous marriages among Muslims in the UK today. The programme examines the daily challenges of polygamous life and the motivation of those who are looking for another wife. It considers whether they are compelled by desire or tradition and meets those who are trying to make polygamy acceptable to mainstream UK society. The film poses difficult questions, not only around reconciling Muslim values with modern British society but also on questions of duty, love and betrayal.
