In the wake of the Mag Lev bombing that killed his daughter, Daniel Graystone (Eric Stoltz) plunges himself into work. He tries to figure out why he can only create a single intelligent robot, not understanding that the answer lies within the fact that part of his daughter survived the explosion & is closer to him than he could imagine. Consumed with grief, Amanda Graystone (Paula Malcomson) is obsessed with discovering who her daughter really was & slowly begins piecing together the details of Zoe’s life. Zoe (Alessandra Torresani) trapped in the robot body, turns to her friend Lacy (Magda Apanowicz) for help. At the same time, Headmistress Clarice Willow (Polly Walker)
- a secret member of the shadowy " Soldiers of the One" terrorist group
