Matthew and Mason are on vacation in Greece with their parents. While exploring the ruins at Knossos Palace on the island of Crete, they wander off and suddenly find themselves at Knossos in its prime, 4,000 years ago, when the Minoans were in power. Captured by guards, they barely escape execution and are forced to join a team of slaves who are training as bull dancers. That means they have to dance with a live bull in front of Minoan royalty. Mason is picked to be a bull leaper along with a girl named Bracche. They have to vault onto the bull's back and off again without getting gored. Will they be able to survive this ordeal, and is there any chance they can escape and take the other members of their team with them?
