Three schoolchildren accidentally find a magical portal in the Holy Trinity St. Sergius Lavra and are carried away into the past. Now their goal is to return home, and for this they need to go through the wonderful forest of the XIV century during the Tatar-Mongol yoke and the Battle of Kulikovo. St. Sergius of Radonezh will help the teenagers.
Sorry, but for now we weren't able to find movies like Forgotten Miracle.
