In 2356, after the AI war, humanity fell apart. Agent Stella (codename White Dove) went undercover to rescue her comrade 'Owl' trapped in Sol Prison. Stella transformed from a bullied newcomer into a force that united the female prisoners into a sisterhood through fists and faith, only to discover that Owl had been tortured to death. With the covert help of undercover captain Elaine, Stella led the women in planning an escape. When her teammates sacrificed themselves to cover her, Stella realised that surviving wasn't for herself, but to bring everyone home. In the end, she set off explosives and led her sisters to true freedom.
