Emily is terrified about losing her first tooth. Her terror escalates when she realizes that a gruesome lady who goes by the name Tooth Fairy is after more than just her teeth.
Jane doesn't quite believe the magic bean is real when the tooth fairy accidentally drops it into her sister's bed. She plants it anyway and finds herself climbing to the sky on a giant beanstalk, just like her cousin, Jack. The Giant catches her and gives her an ultimatum: steal her weight in gold from the dragon or never go home again. Fortunately for her, there are good friends to be had, but will they be enough to overcome an ancient dragon? Jane is determined to try.
