In their darkest days, they'll find the courage to carry on...

Summer 1940
The war is raging on but the Steel Girls are fighting their own battles closer to home. After patching things up with Archie, Patty is miffed when he appears to have forgotten all about her 18th birthday.

New girl Hattie has a lot to deal with as she trades the counter at Woolworths for the Vickers factory floor. But is she keeping a secret and are things tougher at home than she's been letting on?

Meanwhile, Nancy is besides herself when she receives word that Bert is missing in action and is struggling to keep it together.

As the Steel Girls come together to be there in Nancy's hour of need, will life ever be the same again?
