READ MOREIn the documentary One-Way Ticket to the Caliphate, Dutch families with members who have left for the IS caliphate tell their story for the first time. So far we have only heard anonymous reports. Now five people speak openly with documentary filmmaker Hetty Nietsch about their sorrow and sense of powerlessness, and about the outside world that regards this sorrow and sense of powerlessness with suspicion. How could they have failed to notice? Surely they could have seen it? Or did they turn a blind eye because they did not want to see it? The documentary answers these questions and paints a picture of the complex dilemma and harsh reality faced by the forsaken families.
