This fantasy is based on an old forgotten game that gives you magical abilities for your whole family. Walter Budwing (12 years old) and Danny Bobo (13 years), imagine they will be bored when Tim Robbins (Tim Robbins), their father, calls off on business and tells them to stay at home. Walter doesn't really have any use for Danny and is driven by boredom when he offers to play the board game Danny found in his basement while playing hide-and-seek. The boys soon discover that Zathura, a space-themed board game, has unusual characteristics. A roll of the dice suddenly launches Budwing into outer space. Walter and Danny find themselves fighting off angry aliens and menacing robots. The boys are trying to find their way home when they encounter Dax Shepard, an Earthling Astronaut who also has lost his way.
