This observational documentary sheds light on a lifestyle that is often sensationalised. There are now a reported one and a half million people on the British swinging scene, the rise of the internet means it's no longer just about leaving your keys in a bowl, and many major towns and cities in the UK boast swingers' clubs. This intimate one-off programme takes an honest and no-holds-barred look at one of Britain's most popular swingers' clubs: what kinds of people attend and why? Swingers follows the men and women, from all backgrounds, at the club's big Valentine's Day party to find out. Swingers - Monday at 10.00pm on Channel 4.
