Rosie and Vincent Boyd want a baby. They've thrown away the condoms and redecorated the spare room. They've given up red meat, invested in loose fitting underwear and timed their sex to the second. But can they conceive? Not only is the baby extremely reluctant to come but their otherwise happy marriage is beginning to crack at the seams. Not a good time, you might think, for a charismatic Frenchman to re-enter Rosie's life or for Vincent to start up an affair with a hairdresser he once knew. Things can only get worse for Rosie and Vincent... a lot worse before they get better!
