On 17 October 2013, teenage sisters Ayan and Leila Juma left their family home near Oslo, seemingly as usual. Later that day they sent an email to their unsuspecting parents, confessing they were on their way to Syria. They had been planning the trip for months in secret.

Asne Seierstad - working closely with the family - followed the story through its many dramatic twists and turns. This is, in part, a story about Syria. But most of all it is a story of what happens to apparently ordinary people when their lives are turned upside down by conflict and tragedy.
