Penelope, a student reporter, struggles to find her identity after a childhood of tragedy. Desperate to prove herself to her peers, she chases a story tip on a secret organization of teen urban explorers called "The Broken." The group demands she complete a test before they'll let her write the story. While following the clues of their twisted scavenger hunt, she encounters Lex, a paranormal investigator with a knack for hacking. As the pair works together to uncover the organization's darkest secrets, they learn-too late-that the group's plans are much more deadly than they'd realized, and Penelope will have to fight for her own life and the lives of her friends as she learns what it means to be one of the broken.
