Description: Fred, Sam and Samantha travel back to late 17th century Russia to search for the Star of Vladivostok. The star is a great ruby that used to belong to the family of Sam and Samantha's Grandpa Dima. Their search brings them in contact with Peter the Great who is trying to bring technological reforms to Russia. They become involved in his plans to build St. Petersburg but discover that the leader of the rebels who oppose Peter is their ancestor Alexander Kikin...who Peter has sentenced to death. When Sam's grandfather tells them about a lost family treasure, Fred and Samantha convince Sam that they should journey back to 1691 Russia to investigate further. There they meet Sam's ancestor, a guardsman for Tsar Peter the Great.
