One day in 1969, Alan Paris, a 12-year-old boy, accidentally found the "Umanji" game chess buried in the soil on the construction site of his father's shoe factory and brought it home. Allen had a dispute with his father, and was about to run away from home, and his friend Sara came, and the two played "Umanji" together. Once the dice were thrown, the chessboard showed an incredible magic: Allen was caught by the chessboard. Engulfed, Sara was driven out of the room by a group of scary bats.
Twenty-six years later, Judy and Pete moved here, and they found the "Umanji" chess. After studying the rules of the game, they found that the game cannot be stopped once it starts, and can only be played step by step to the end. The siblings can only continue the game that Allen played back then. After the dice were rolled, a lion and Allenbeen imprisoned for 26 years, ran out. Allen, who had subdued the Lions, was extremely happy, but soon discovered that something was wrong. First, things are not humans, and secondly, the game has attracted a large number of wild animals to turn the town upside down. With the mobilization of the Judy brothers and sisters, Allen found Sara and determined that the four of them will carry out the game to the end. The dice were thrown out again and again, and various disasters and dangers appeared one after another. The four people struggled with it with wit and bravery. In the end, the dice stopped to an appropriate number and the game was over. Allen and Sara also became children and returned to 26 years ago.
Allen and Sara threw the "Yumanji" chess into the river and returned home to live their peaceful lives. On another remote river bank, "Yumanji" was lying quietly, waiting for its next customer.
