The plot is pretty simple and innovative: Jumanji is the name of a game which, when played, has real-life consequences. These consequences include slithering vines, mischievous monkeys, stampeding elephants and rhinos, giant spiders, monsoons, and human hunters. Williams plays the character of Alan Parrish, who is literally sucked into the game when playing it. Thought dead by his parents, he is lost in its confines until he is brought back by two new gameplayers, siblings Judy (Kirsten Dunst) and Peter (Bradley Pierce). The story is essentially about how Parrish and his new compatriots finally manage to win the game in the nick of time.
Have fun !!!
