Brantford High School is the high school attended by the four kids who got sucked into the video game. It is run by Principal Bentley.
Twenty years after the disappearance of Alex Vreeke, four students in Brantford High School are placed in detention together: Spencer Gilpin, who is writing essays for his former friend, Anthony "Fridge" Johnson (who is also in detention), and Bethany Walker & Martha Kaply, who have both disrespected their respective teachers during class. Under directions of Principal Bentley, the quartet are assigned to clear out the school's basement, as it is about to be turned into a new computer lab. Their main job was to remove the staples from the magazines in the bin. But while they were doing the job they were forced to do, the four find Jumanji, a five-player action-adventure console game. With one of the playable characters (video game avatars) inaccessible, the teens select the others, and are sucked into the game.
Once the game ends, the four teens and Alex reverted back to their former selves and returned to the real world. The four teens returned to the school basement where they first discovered the game, but then they discovered that Alex did not come with them. On their way home, they reveal that the Vreeke household – once abandoned with Alex's disappearance – has been restored. An adult Alex appears; he emerged in 1996, and history was changed. He is now married, and named his eldest daughter after Bethany in gratitude of saving his life before leaving Jumanji.
Spencer and Fridge reconcile, Bethany becomes a more empathic person and makes plans to go backpacking from her experiences in the game, and Martha starts dating Spencer. The four hear Jumanji's drumbeats, but they take the game behind the school, and destroy it with the Rhino bowling ball they found in detention.
