About the title
Three schoolchildren accidentally find a magic portal in the Holy Trinity–St. Sergius Lavra and are swept into the past. Now their goal is to get back home, and to do so they must pass through the wondrous forest of the 14th century, in the era of the Tatar-Mongol yoke and the Battle of Kulikovo. Helping the teenagers along the way will be Saint Sergius of Radonezh.
