I can't find a movie I used to see. It was about girl-machines who thought that they would go to the "happy place" when they finished their service. One of them meets a guy who tells her this isn't true. He takes her to a factory to show her that old machines are sent there instead of the "happy place". It turns out that old machines are actually being utilized to become food for new ones.
In 2144, Sonmi-451 is a "fabricant", a human cloned for slave labor, kept as a fast food server in a dystopian Neo Seoul. She is exposed to ideas of rebellion by another fabricant, Yoona-939. After Yoona is killed, Sonmi is rescued by rebel Commander Hae-Joo Chang, who exposes Sonmi to the banned writings of Aleksandr Solzhenitsyn and a film version of Cavendish's experience. Hae-Joo eventually introduces her to the leader of the rebel movement, and shows her that clones are recycled into food for other clones.
A couple of stills of Sonmi and Yoona from the movie:
You can also see some scenes of Sonmi-451 in the extended trailer:
There's another glimpse of Sonmi and Chang at 2:37. (Thanks to InvisibleTrihedron for the pointer.)
