Jess is nearly forty when she meets Dan Harris at a party. She is single, sorted, happy - with a great job and a buzzy social and sex life. All of this is threatened when she falls deeply in love with Dan, who is only twenty-three.

Jess, being older, recognises this as the real, precious thing - but in his immaturity, Dan does not. Unable to cope with the stigma of being with an older woman, he eventually leaves her.

Ten years pass...

Jess, who is still gorgeous at fifty, is married now, with a child of her own. They meet again. The years fall away.

This time, Dan understands - but is it too late?
