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 her only belongings are crammed into a small suitcase. Among them is one precious photograph of the family she has left behind in Germany. Lonely and homesick, not knowing if she will ever see her family again, Lisa is adopted by a childless couple and then bullied at school for being German. But worse is to come when the Blitz blows her new home apart and she wakes up in hospital with no memory of who she is, or where she came from. 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?
