One single man and one single woman are going to meet each other's friends, family, and ex-partners. They will stay in each other's homes and be given free access to each other's emails and social networking sites. By uncovering the behavioural patterns and emotional make-up of a total stranger they will get the greatest insight and a fresh perspective into the reasons behind their own dating disasters and wrong turns when it comes to finding love. When the two strangers finally meet in a dramatic and stylized union they're going to have the ultimate answer to each other's big question; You are still single because...! A few weeks later we will return to see if confronting the truth about their relationship failures has given them the insight they really needed, have they finally found lasting love? Does learning about someone else's love life hold up the clearest mirror to your own? What's it like to have someone digging around in the most private parts of your past? And what happens when you allow someone else to make a decision about who you should be with? This warm, witty and revealing programme unveils all.
