Family adventure starring Jonah Bobo and Josh Hutcherson as two brothers, Danny and Walter. Despite their squabbling, the brothers manage to cooperate enough to play an old mechanical board game named Zathura. However, after their first move, they find that the game has apparently flung them, their sister and their entire house into outer space. Furthermore, the brothers surmise the only way to return home is to finish the game. However with almost every move, new dangers arise as the siblings find themselves learning to cooperate in ways they never expected as they realise what they mean to each other.
