Plot summary Four high-school students discover an old video game console and are drawn into the jungle setting of Jumanji, becoming the adult avatars they chose. Spencer becomes Dr. Bravestone (a strong archeologist), Fridge becomes Franklin "Mouse" Finbar (a zoologist and cartographer), Martha becomes Ruby Roundhouse (a combat-trained dance fighter), and Bethany becomes Professor Shelly Oberon (an expert cartographer and cryptologist). Guided by a non‑player character, Nigel (later revealed to be the game’s longtime avatar), they must complete the game by returning a magical jewel to a statue and restoring order to the world. Along the way they face dangerous creatures, solve puzzles, learn to work as a team, and confront personal insecurities. The film alternates action, humor, and character growth, concluding with the teens back in the real world having learned from their in‑game experiences.
