Because his father had to go out for work, his sister Lisa (Kristen Stewart) had to take care of his two younger brothers Danny and Walter as the eldest. However, Lisa was lazy and left Danny (Jonah Bobo) and Walter (Josh Hutcherson), two active and naughty young guys, to go upstairs to sleep. The two bored people had to entertain themselves, but their constant quarrels made Danny leave in anger and go to the basement alone to find a set of space flying chess. Danny turned on the game out of curiosity and invited his brother Walter to join the game. The constant meteor showers and alien invasions made the game more thrilling, and the true identity of the mysterious astronaut who joined in the middle was even more surprising. Gradually, they realized that this was not an ordinary game of chess, and once the game was turned on, if they could not reach the end of the game, the planet Zathura, they would be stranded in outer space forever. So can the two brothers put aside their past grudges and work together to overcome difficulties in this real adventure? This film is the second part of "Jumanji", adapted from the work of the same name by the famous writer Chris Van Allsburg.
