Cherry Healey wants to find out what a modern relationship looks like in a world where anything goes. Does single equal sad and lonely or is it free and sexy? Is coupledom the mark of success or is staying faithful to the same person forever now just plainly absurd? Cherry wonders, on meeting some serial daters, just how many is too many? She also spends time with identical twins, one single and one married, teenagers who are into threesomes and a young man who is desperate to meet 'the one'. Can she get to the heart of things and find whether they all really prefer being single or settled?
