Nat doesn?t want babies; she accepts this is unusual, but not unnatural, which seems to be how everyone else is looking at the matter. She has her reasons; deeply private & personal ones, her husband Neil has always been in complete agreement with her decision. But then Neil has a change of heart & now longs to become a dad. Nat can't or won't give him what he wants; she can't or won't even explain why. Cracks start to appear in their relationship & Nat begins to question if the man she married is the man she's meant to be with.
