The story begins when a scientist rebuilds a female cyborg with no memory of her past, except for her deadly martial arts skills. She then goes around fighting crime. Obviously things get complicated and I'm sure memories of her past come back to haunt her.
Condor (who had a very small role as Jubilee in X-Men: Apocalypse) joins a cast that already includes Rosa Salazar, Jackie Earle Haley, Ed Skrein, Eiza Gonzalez, and Christoph Waltz. The film has been slated for release in July of 2018.
