The mystery of the red tent

During a visit to the Moon Park, the older sister of the schoolboy Yasha enters the red tent-play a fascinating game with a valuable prize-and disappears without a trace. Small dreams are dreaming, and no one believes in the story of the tent. To find a sister, Yasha decides to enter the game himself and, together with her friend, Tanya enters the mysterious country of Isfaria. Not only his own fate depends on whether Yasha can pass the game to the end and make the right decisions, but also the life of his sister and friends, and even the prosperity of Isfaria itself.
