It starts with four high school kids going to detention. Their punishment is to clean the basement of the school, but while down there, they find a very odd-looking old video game system. Yes, Jumanji is no longer a board game. They turn it on and each student (the nerd, the jock, the pretty girl, and the quiet girl) picks a character to play as. After they select, they are sucked into the jungle. The nerd turns out to be Dwayne Johnson, the jock is Kevin Hart, the quiet girl is Karen Gillan, and the pretty girl is Jack Black. That last bit, of course, is played for a lot of yuks.
They realize that, because they are in a video game, they each have video game powers. For example, Johnson’s character is super strong and Gillan’s character is a dance fighter, which they joke about. And also, she very quickly acknowledges how ridiculous it is that the game makes her outfit so skimpy. A kind of guide character tells them they have to place a jewel back into a statue to leave—but as they progress, the challenges get greater and greater. Killer animals, evil men on motorcycles, just lots of crazy stuff. And, like a video game, they each have three lives. If they lose those, they die for real.
The whole thing has a kind of Indiana Jones for kids vibe. Lots of jungle settings, lots of action, running and jumping. Slow motion fights, flame throwers, machine guns. We meet Nick Jonas’ character who seems to know his way around really well. Later we see him flying a helicopter with the main characters on it, through a canyon that has a hippo stampede happening. One of those hippos eats the Jack Black character in another scene, seemingly taking one of his/her lives.
Oh, and at one point, the guide character mentions someone who spent a good portion of time in the game. Someone named Alan Parrish—aka, Robin Williams’ character from the first movie.
