Follow high school student Courtney Whitmore (Brec Bassinger), along with her stepfather, Pat Dugan (Luke Wilson), as she leads an unlikely group of young heroes to take on the legacy of DC’s very first Super Hero team, the Justice Society of America. The final season finds Starman (Joel McHale) back from the dead and offering to train Courtney while she helps him adjust to his new life in the quiet town of Blue Valley. But when there’s a murder that needs to be solved, the mystery will not only have our heroes questioning the former Super-Villains’ commitment to truly reforming but will also lead Courtney, Pat and Starman to a secret that will shock each of them to their very core.
