Frieda, a (mostly) obedient girl from Heidelberg, travels across the seas with her adventurous father and sickly mother to live Adelaide. As she embarks on a mission to make some friends, World War One breaks out and the Germans, once considered friends of Australia, are now the Enemy. Rumours circulate that Frieda’s father is a German spy, and the local children form the Junior Anti-Hun League. Should Frieda change her name and hide all trace of her culture? Or will her new friends stand by her?
