The new one-hour scripted action drama follows Chloe King, who is looking forward to celebrating her 16th birthday with her friends and single mother -- just like every other year - that is until she starts developing heightened abilities and discovers she's being pursued by a mysterious figure. Chloe soon learns she's part of an ancient race called the Mai, which has been hunted by human assassins for millennia - and that she may ultimately be their only hope for survival.

In an effort to distract her from the madness her life has become, Chloe accepts another date from Brian. She knows this not only puts her life in jeopardy, but his, and still she can't resist. However, once Chloe receives a mysterious call on her mother's cell phone from The Rogue, her priorities shift. In turning to the Mai for help to locate The Rogue, Chloe asks Alek to protect her mother, who obliges, thus intensifying their blossoming relationship. Meanwhile, Valentina has instructed Chloe to stay at her home under the watch of Jasmine, in order to protect her remaining eight lives. Chloe knows she must follow orders, but when family and friends become involved, the teenager takes matters into her own hands, possibly endangering the existence of the Mai and herself.
