Young soccer player Dolf fails to score in the European junior championships, causing his team to be eliminated. He visits his mother's lab as she tests a time-travel machine. Dolf travels back 12 hours to replay the match, but accidentally ends up in the year 1212. Saved from bandits by the beautiful Jenne, his first attempt to transport home fails. Dolf joins Jenne and thousands of children on a pilgrimage known as the Childrens Crusade. Finding his modern perspectives both a help and a hindrance, Dolf is alternately viewed as a miracle worker and the Devil s disciple. Back in the present, his mother studies historical documents to arrange a rendezvous to bring Dolf home. While the journey is fraught with hardships, battles, treachery, and sacrifice, it is also a place where friendships are forged and a romance is born. His last chance to return home, Dolf rushes to make the rendezvous with Jenne in hand. Will Dolf return home safely with Jenne by his side?
