1942. A German aircraft crashes into a house in Worthing, and causes complete devastation to the local community.

Three strangers meet for the first time that day – Pip, Stella and Lillian. Lillian's little girl Flora has been hurt in the crash and is rushed to hospital. As she comes through her ordeal, she finds her mother and her two new ‘aunties’ by her bedside.

The three new friends quickly bond over shared experiences; all their husbands are overseas in the fighting forces. They also have the same love of singing and soon form The Sussex Sisters, Worthing’s answer to the Andrews Sisters, to boost morale in in dance halls and canteens all over the south coast.
