Filmmakers: David Herdes & Zanyar Adami

Zanyar is a magazine publisher based in Sweden. He is about to become a father but before his baby is born he needs to confront his own father, Taher, about why he sent Zanyar to Europe on his own when he was just five years old. At the time, Taher was fighting with the Kurdish rebel forces in Kurdistan.

In 2009, some 300,000 refugees crossed the borders into Europe; a third of these were unaccompanied children from countries such as Afghanistan and Iraq. Now, Taher drives a taxi on the roads of Stockholm. He does not talk about his past as a Kurdish fighter or the sacrifices he has made. But Zanyar slowly unpicks his story.

This is an intense and intimate film about an emotional journey, as a son learns about his father’s past and the two explore each other's feelings, before the next generation arrives.
