Dolf (Flynn) goes back in time and joins a band of travelling children on a crusade to Jerusalem. He is put on trial after a rescue mission ends up with a child being seriously injured (and because the bad guy thinks he is an heretic!).
The film is also Known as 'Crusade in Jeans' (USA) or 'Kruistocht in Spijkerbroek' in The Netherlands (the country in which is was made). Nice little film, with a cute shirtless guy who gets tied up!
