Thirteen-year-old Lisa escapes from Nazi Germany on the Kindertransport and arrives in England in August 1939. She can't speak a word of English, and among her meagre belongings is one precious photograph of her family. But when the Blitz blows her new home apart, she wakes up in hospital with no memory of who she is.
The authorities give her a new name and despatch her to a children's home. With the war in full swing, what will become of Lisa now?
