Crusade in Jeans

Based on a multi-award-winning novel by Thea Beckman which received the Youth Literature Award among other accolades, this film tells the story of 15-year-old Dolf who finds himself accidentally catapulted from the present day back into the 13th century, where he has to try to hold his ground amidst the turmoil of the Children's Crusade which, according to historians, took place in 1212.
Dolf's mother is a researcher. After they have a row one day, her son misuses her latest invention of a time machine to try to get to a football final on time, but finds himself transported instead to the past. All at once, 8,000 children are on the old Roman road on their way to Jerusalem in order to 'liberate' the city from Muslims. And Dolf is one of them! If he hadn't run into a girl of his own age named Jenne he would have been completely at a loss. But with Jenne's help, he learns to cope with life in the Middle Ages. Against his better judgement Dolf even finds himself among the leaders of the campaign. The priest, Anselmus, is convinced that the boy has been sent by God. But should Dolf put his faith in this religious zeal? (Berlinale)
