Life felt unfair for a 13 year old boy in New Jersey, USA – until he visited a fun fair and made a wish on a mysterious antique arcade machine called, Zoltar. His wish was to be “big”, in an attempt to not endure the unfairness of being a teenager.

After wishing to be made big, the boy wakes the next morning to find himself mysteriously in the body of an adult (played by Tom Hanks), despite his protests he isn’t recognized by his own mother and so has to make a hasty exit from the family home shared with his mother and sister. The film then follows the twists and turns of a child in an adult world, with some help from his best friend.
