Frankie Gaines may appear to be just like any other teenager, but she is hiding a big secret: she is actually an experimental android developed to look like a real human being.
Her creator is Sigourney Gaines, a scientist working for an shadowy tech company called EGG Labs. When she learns of EGG's plans to use Frankie in a military project, she quits her job and brings Frankie along with her, moving her family far away to give Frankie a normal life.
To ensure Frankie's safety, Sigourney poses as her mother and enrolls her in high school. Keeping up appearances takes a lot of work, and thankfully Frankie's new best friend Dayton is there to help her deal with the social pressures and information overload.
