It's the mid 1950s & Helen's husband Jack returns from National Service. Happy to be reunited, they resume their life together. Their friends, Lily, pregnant & married to Jack's brother Martin, Katie, pregnant & married to Helen's father John, & Judy, engaged to policeman Sam, form part of their everyday life. Then Helen is utterly shattered when Jack tells her that a brief fling with a sergeant's widow has left the woman pregnant. Helen can't have children so handling her friends' pregnancies has been difficult enough; this is more than she can bear. She starts divorce proceedings but their fierce love for each other cannot be extinguished. Finally she has to make a decision which requires courage but could be the answer to their differences.
