This feel-good musical is based on the classic Tom Hanks film of the same name and follows a twelve-year-old boy named Josh Baskin, who thinks his life as a kid is dull. One night while at a carnival, he tosses a coin into a Zoltar fortune-telling machine and makes a wish to be 'big'. But after the arcade-like machine says his wish has been granted, Josh is shocked to find it had been unplugged the whole time. Shaken from this revelation, he returns home and goes to bed, only to wake up the next morning as a fully-grown, thirty-year-old man. Forced to do what normal adults do and get a job and a girlfriend, Josh soon begins to wonder whether it's actually worth being all grown up after all.
