In the 1960's a young boy named Alan Parish finds an old board game called Jumanji. He plays it with a girl he likes, then vanishes into the game for twenty-six years. In that time, two kids named Judy and Peter move into his house with their neurotic aunt and find Jumanji. They play it and release Alan, now a thirty-something year old man (Robin Williams). The catch to Jumanji is that the things that come out of the game -monsoons, stampedes, bloodthirsty hunters and more- can go away only if the game is finished. Alan reunites with the girl he started to play the game with and they must work together to finish the game and rid their world of the danger it's fallen into.
