The story begins with a mysterious board game, "Jumanji," which has been collecting dust in a young boy's attic for 26 years. The game is said to have supernatural powers, drawing players into the jungle-themed world of the game itself. When two children, Peter (Adam Hann-Byrd) and Judy Shepherd (Kirsten Dunst), unleash the game, they inadvertently awaken a man, Alan Parrish (Robin Williams), who has been trapped inside the game for 26 years.
