When four high-school kids discover an old video game console with a game they've never heard of--Jumanji--they are immediately drawn into the game's jungle setting, literally becoming the avatars they chose: gamer Spencer becomes a brawny adventurer (Dwayne Johnson); football jock Fridge loses (in his words) "the top two feet of his body" and becomes an Einstein (Kevin Hart); popular girl Bethany becomes a middle-aged male professor (Jack Black); and wallflower Martha becomes a badass warrior (Karen Gillan). What they discover is that you don't just play Jumanji--you must survive it.
