Sunderland, 1942: Polly's heart and her future are hanging in the balance…

Polly’s sweetheart Tommy has been declared missing while serving overseas, and although there is no certainty that he is dead, there is no guarantee that he will return home. Now Polly needs her friends more than ever, and the other women welders are ready to rally around her while she waits for news.

The only one not showing support is shipyard manager, Helen. But looks can be deceiving, and beneath her cold exterior, Helen is wrestling with demons of her own, including one life-changing decision that could lead to potential ruin.

As the war continues, the shipyard girls must support one another as they bravely soldier on.
