Tomorrow Jones, 14 years-old and the second child in a family of superheroes. While she may be strong enough to fold an armored truck into origami, Tomorrow has to pretend to be a normal girl at school. Her father won't take her seriously, and her traditional heroine mother expects Tomorrow to follow in her footsteps. But Tomorrow doesn't want to dress in skimpy spandex though, and starts fighting crime unmasked and simply wearing jeans and a T-shirt with her real initials on it. All the while her parents keep trying to get her to do things "the traditional way" and Tomorrow finds she might be getting in over her head in the superhero community.
