How do you know when you've met the one you're meant to be with? Neil and Nat are a match made in heaven. They hate marmite and the opera. They love smelly cheese and the missionary position. And they both absolutely do not want children. At least that's what Nat thought. But now Neil seems to have softened to the prospect of dirty nappies and sleepless nights, and he's practically begging her for a baby. Nat, however, has no intention of swapping her high-flying career for a life of endless self-sacrifice. As the cracks start to show, Nat wonders if Neil really is the man of her dreams. Or is it possible that someone from her past could actually be 'the one'?
