Series 1

Nine pairs are cuffed together as the experiment begins. There's a sweary bar-tender and a millionaire. An alpha male and a proud feminist. Who'll be first to take the cuffs off?

Self-confessed prude Charlie is hooked to heavily tattooed Rob. Can Christian hairdresser Nina handle Sara's chatty nature?

Horse trainer Claire believes in country air and hard work. Bambi, a city-loving model and content creator, likes the easy life. Can Bambi keep up with Claire's schedule?

Can an eco-warrior and a petrolhead beauty salon owner agree to disagree on the environment? And a country-loving Yorkshireman shocks a London youth worker to the core.

The handcuffed pairs go on a road trip, away from home and family, just the two of them and the iconic, idyllic great British outdoors. Naturally, tempers flare.

It's the final. With a race across Britain and a £100k prize at stake, how do the pairs work together? Do they bond? Or do tensions boil over? And who will be Handcuffed champions?
