After the death of their parents, inseparable twin sisters Anna and Lotte are cruelly separated at the age of six. Anna remains in Germany, growing up in harsh circumstances on her uncle and aunt’s farm, while the sickly Lotte is given a loving home in the Netherlands by wealthy distant relations. In the years following their separation, the girls try desperately to get in touch with one another. Briefly reunited years later as young women, it becomes apparent that they have led very different lives. When WWII breaks out, the gap widens further as the sisters find themselves on opposing sides.
