Synopsis
Courtney Whitmore (aka Stargirl) is smart, athletic, and above all else, kind. This high school teenager's seemingly perfect life hits a major speed bump when her mother gets married and her new family moves from Los Angeles, California, to Blue Valley, Nebraska. Struggling to adapt to a new school, make new friends and deal with a new step-family, Courtney discovers her step-father has a secret; he used to be the sidekick to a superhero. 'Borrowing' the long-lost hero's cosmic staff, Courtney becomes the unlikely inspiration for an entirely new generation of superheroes. STARGIRL follows high school sophomore Courtney Whitmore as she inspires an unlikely group of young heroes to stop the villains of the past. This new drama reimagines Stargirl and the very first superhero team, the Justice Society of America, in an unpredictable series. STARGIRL is lovingly inspired by Johns' late sister, who was killed in a plane accident.
