The adventures of three curious boys who are transported back to dramatically different places in history.
When The Book pages transform into rongorongo script, Freddi, Samantha and Fred transport back to 1765 to Rapa Nui (a.k.a Easter Island) and end up facing a 15-ton Moai! It's just another day at the beach as the Trio jumps off cliffs, swims through shark infested waters to the Birdman's Island (Motu Nui), oh and tries to find The Book along the way!
Joe is slowly disappearing because of a malfunction in his family tree. To save Joe, the kids must go to India during the Gupta Empire. Sam, Fred, Samantha and Freddi have to help Joe's ancestor Prince Karna win the hand of Princess Lakshmi to save the entire family line!
A wild warp at the Olympia Diner sends Fred and Samantha to Ancient Greece during the Olympic games. Can Samantha win the pentathalon and save the sacred Olympic truce between Sparta and Athens?
Sam gets trapped inside The Book, and Anna, Fred and Joe travel back to the Tang dynasty in China in A.D. 621 to figure out how to get him out. En route they help the Shaolin Monks rescue General Li Shimin from prison, travel past the beginnings of the Great Wall, learn about the teachings of Zen Buddhism, and come face to face with the evil Mad Jack!
Sam's Grandpa Dima tells some pretty outrageous stories to Sam, Fred, and Samantha about his ancestor, Alexander Kikin — but, are they true? Fred and Samantha convince Sam to travel back to Russia in 1698 just in time to save Kikin (a member of the Russian guardsmen, the Streltsy), from the wrath of Peter the Great.
When the kids warp back to the Stone Age, they manage to decipher some cave-paintings and find The Book in the camp of the Neanderthals. But when they trade Jodie's binoculars to get The Book back something goes wacky and the kids are suddenly a lot hairier than usual.
