The movie takes place in the jungle, where four teenagers - Spencer (Alex Wolff), Bethany (Maddie McGraw), Fridge (Ser'Darius Blain), and Martha (Morgan Turner) - stumble upon an old board game, Jumanji. As they start playing, they're sucked into the game and transported to a virtual world, where they become avatars in the form of Dr. Smolder Bravestone (Dwayne Johnson), Professor Sheldon 'Shelly' Oberon (Jack Black), Ruby Roundhouse (Karen Gillan), and Moose Finbar (Kevin Hart).
