Molly Moon is treated like dirt in her squat English orphanage, with only her pal Rocky, starry Qube soda ads, and the library stacks to give her comfort. After she discovers Hypnotism: An Ancient Art Explained in her favorite library spot, Molly begins learning the ropes and takes mental control of Petula, the orphanage's grumpy pug dog, and the nasty staff members. But when Molly finds out that Rocky's been suddenly adopted in New York, she hypnotizes her way to the city, into Broadway stardom, and -- unfortunately -- into a wicked professor's plot to rob a high-security bank. Thankfully, though, she and Rocky finally meet up, and with a few surprises, the two hatch a plan to set things right for themselves and for their orphanage.
