A small-town teen (Aubrey Peeples) goes viral after a video of her singing is posted to the Internet. She and her sister's band are catapulted into global superstardom, but their newfound fame threatens to break apart their familial bonds when a record executive (Juliette Lewis) meddles in their affairs. This spirited musical fantasy directed by Jon M. Chu is adapted from the 1980s animated series Jem.
