Val doesn't find it as easy as she'd expected to fall pregnant with her longed-for first baby. When Cissie's husband Walter starts taking an interest in a new female colleague, jealousy rears its ugly head. Janice is consumed with guilt at leaving her widowed father and young brother behind in Blackpool to start a new life in Yorkshire.
