Iris Heller, a teenager with Sensory Processing Disorder, runs away to
compete in a national bake-off contest. In order to get there, she
"borrows" her mom's car, travels along the East Coast, and does the most
terrifying thing of all --interacts with actual people! Iris has never
been like other girls, but she's not about to start letting that get in
the way.
Iris has this profound fascination for the musician Dave Matthews, and
she feels a compelling need to compete in the bake-off for Dave. To
compensate for nervousness, she has the habit of humming, beatboxing,
and making musical contraptions out of items around her. It is this
talent that gets noticed at several road stops along the way, which
leads to her inevitable "gone viral" glory. At a donut shop, Iris sings
like an angel. At a coffee shop, she plays a symphony using cups and the
soda fountain. At a restaurant, she builds a glorious musical fountain
out of dishes and pans. Iris is the kind of pure spirit who brings the
best out of the world around her without knowing it.
Iris' mom (Maisy) and her best friend Eric set out to find Iris. All
lives converge at Happy World, the Disney-esque paradise, where the
bake-off takes place. Iris, whose life has been one of isolation and
misunderstanding, finds out just how much she is loved. It doesn't
matter whether she wins the bake-off, she's already won the biggest
contest of all, triumphing in life.
