Fanny's Journey is about a group of Jewish children living in occupied France during World War II, who've been left in a rural safe house by their parents. However, when they are discovered by the Nazis, their adult carers organise for the children to escape to the safety of neutral Switzerland. When the operation goes pear-shaped, it's up to strong-willed 13-year-old Fanny to lead her two younger sisters and five others through the dangerous countryside, unsure of who to trust along the way.
