It’s autumn 1940 and the Blitz has cast its shadow over London. Everyone is doing their bit to help, including the three Harrison sisters of the East End’s Victory Walk.
Nurse Rose is snowed under in the hospital tending to victims of the bombings. Her sister Clover is on active duty on the south coast, while the baby of the family, Daisy, is growing up quickly working on the London Underground, now that thousands of people are taking shelter down below.
Even in wartime, the sisters find time for a wedding, but the bride is keeping a secret, which threatens to come to light. Can the three sisters stick together, for each other, and for King and Country?
