When 10-year-old Joe (Mark Rendall) receives a mysterious book from his eccentric magician Uncle Joe (Tony Daniels), he has no idea the adventures that await him and his friends Sam (Darren Frost) and Fred (Scott McCord) . As it turns out, whenever the kids make a wish, the Book emits a glowing green mist and warps them back through time. Whether they want to go or not, they are thrust into an extraordinary adventure, in which they duel with gladiators in ancient Rome, march in battle with the samurai in Shogunate Japan, meet Blackbeard the pirate on the open seas, or ride on horseback into battle against the Tartars with a young Genghis Khan!
