The Modern British Slave Trade explores the rise of modern slavery in the UK, giving a portrait of the dark world of forced labour through the eyes of the people involved. The British government estimates that there are approximately 13,000 people forced into slavery in the UK today and this documentary provides a unique insight into this hidden criminal world, from the 'slaves' themselves to the investigators and the people who are trying to tackle this criminal industry. From agriculture to nail bars, the programme explores the dark world of modern-day slavery and many of the people trapped in plain sight.
