Several months after their unexpected adventure in the Amazon, Ike is not happy. He’s tired of being picked on and treated like a baby. But when the kids learn that Anatoly has kidnapped a group of innocent children and is holding them ransom in the forests of Siberia, Ike knows he has to do something. But Anatoly is demanding a steep price – that they hand over the globe. When Grandpa suffers a heart attack, Ike, Mary, and Helen know that if they don’t do something to help, the other kids will be in danger. Reluctantly, they determine to use the globe once again. Only this time they leave better prepared. Or so they thought. When they arrive in Russia, they quickly learn that their problems are much bigger than just Anatoly. When a mysterious group of people appear using a second globe, Mary is kidnapped, and now it is up to Ike and Helen to cross the vast country and find her.
