The adventures of three curious boys who are transported back to dramatically different places in history.
The boys in this episode are transported to North America during 1000 A.D. It is before Christopher Columbus discovered America. They meet Viking explorers who are led by Leif Erikson.
The boys go back in time to 1877 when the Brooklyn Bridge is being constructed. They discover that they are trapped on top of the bridge.
A basketball game gets interrupted and the boys find themselves in Chichen Itza, Mexico in the middle of a Mayan ringball court a thousand years ago! Of course in this game, the stakes are a little higher because if they lose, they lose their heads!
Joe and Fred warp back through time to Paris, France in 1815. There, they get to meet Napoleon, an emperor, and Sophie Blanchard, a hot-air pioneer.
Joe, Fred and Sam warp to Babylon to figure out who stole The Book and to meet King Nebuchadnezzar II and Queen Amyitis, the creators of the Famous Hanging Gardens. Can they recover The Book before all of Babylon is destroyed and Joe's evil uncle Mad Jack takes over the world?
Fred and Sam, playing around with the ancient artifacts in Joe's father's office, accidentally transport themselves into the middle of a tribal battle in the African country of Angola in 1624 A.D., where they become slaves of Queen Jinga (who prefers to be known as King Jinga) and have a chance to explore the famous Kwanza River and witness a historic meeting with the Portuguese colonial governor.
