Instead of chopping down the old fruit tree like his aunties asked, James discovers a magic potion that makes an old peach grow to an enormous size. After finding a door to climb inside, James meets a group of outrageous oversized insects who’ve made the peach their home. James and his newfound friends decide it’s time to leave the Aunties, and we follow them as they roll their peach into the ocean and embark on a fantastic voyage that lands them on top of the Empire State Building.
