As Chang falls asleep, Sonmi attempts to take in the day's chaotic events, during this time she cuts off the colored strand of hair that marks her as a "replicant". Being unable to sleep, she walks over to Commander Chang and puts her head to his chest in order to hear his heartbeat, this prompts Chang to wake fast and grab her, Chang and Sonmi then engage in intercourse, starting an intimate relationship between the two. in the weeks to follow he and Sonmi enjoy much time together until the Union revolutionary group decides it's time to make their move.
Later in the day, Chang finds two red jumpsuits which he and Sonmi use to disguise themselves as factory workers and enter a very eerie looking facility. when inside Chang takes Sonmi up to a catwalk, when they look down, they see thousands of replicants in white hooded robes marching with candles and singing. Sonmi recognizes this as the release to a better life promised to all replicants,but is informed by Chang that it is not what it seems. Chang proceeds to lead her to a room in which a replicant is seated by factory workers, who promise her that she is ascending to something better, they then execute her, and send her body deeper inside the facility. After being lead to deeper inside by Chang, Sonmi watches in horror as thousands of replicant's bodies are stripped, dismembered, and ultimately ground up. Chang informs her that after reaching a certain age, replicants are sent to facilities like this, and turned into food for the still living replicants, and this is what the Union Revolutionary Group is fighting against, after all this, she's ready to serve the Revolutionary Group.

Chang takes a squadron of Union Revolutionary soldiers and successfully takes over a broadcast station, he and the soldiers barricade the entrance, set up a line and wait for the military to attempt to retake the station. When the military gains entrance Chang along with his whole squadron are killed after a long firefight, with Sonmi tearfully watching Chang's demise. Before he died defending her, the two exchanged one last glance.
