An 11-year-old dreamer participates in a big fundraiser to save her school's failing art program, and scrambles to recover her missing diary in this adaptation of Jim Benton's popular youth fiction series. Jamie Kelly (Emily Akyn Lind) may not be the most popular girl in Mackerel Middle School, but in her dreams she's so glamorous that even her popular classmate Angeline (Sterling Griffith) is green with envy. Meanwhile, back in real life, Jamie's crush Hudson Rivers (David Mazouz) never even gives her a second glance. Fortunately between her beloved Aunt Carol and her loyal classmate Isabella (Mary Charles Jones), Jamie has the best friends a girl could ask for. Later, when Jamie learns that Mackerel Middle School will be staging a Jump-a-thon fundraiser to keep its troubled art program afloat, she senses an opportunity to stand up for the less popular crowd. Jamie learns a couple of valuable life lessons, however, when her treasured diary disappears without a trace, and one of Isabella's ingenious schemes goes horribly awry.
