Crusade in Jeans

Crusade in Jeans is a 2006 Dutch film directed by Ben Sombogaart. It is an adaptation of the book Crusade in Jeans by Thea Beckman. Plot Dolf is a 15-year-old boy from Rotterdam who plays for the junior national football team. At the beginning of the film, Dolf and his team are playing an important championship game against the Belgian team in the German city of Speyer. They were trailing by a goal, and got the chance to equalise in the final minutes which Dolf blew. Dolf's mother works in a research centre in Rotterdam where a time machine has been developed. It allows an object, animal or person to be moved to a specified time and place in the past, and to bring them back again. But, a person moving to the past can only return to the present by being at an exact location at an exact time. Furthermore, a special medication is needed daily to stay alive in the past. Dolf decides to go back in time one day to replay the match, since he regularly visits his mother at the lab, assists with the work, guards know him, the iris scan authorization check lets him pass, and he knows his mother's password to the computer system. However, the activation of the system alarms the guards. Dolf manages to operate the machine just in time before the guards can stop him, but in his haste he accidentally enters the password instead of the destination date, and consequently travels to the year 1212. He ends up at the location of the present-day football stadium, not far from the city of Speyer, which already existed then.
