Four women, linked by blood ties, friendship, betrayal, loss and hope, struggle with the choices they've made and the hand that life's dealt them.

All Pippa's ever wanted is marriage and kids, but at thirty-four and about to embark on IVF, her dream of having a family is far from certain. Her younger sister Georgie has the opposite problem, juggling her career, her lover, a young daughter and a husband who wants baby number two.

Pippa's best friend Sienna has a successful career in the film world, and despite her boyfriend pressurising her to settle down, a baby is the last thing she wants. Happily married Connie shares the trauma of fertility treatment with Pippa, but underestimates the impact being unable to conceive will have on her and her marriage.

As their lives collide in a way they could never have predicted, will any of them get to see their hopes realised?
