On the night of 18 January 1960, Aether President Lusamine enters the Team RR castle. Soon after arriving, Lusamine is summoned to the office of the leader, Giovanni, who warns her that she can’t escape this castle for its exceedingly high level of security. According to her kids, Lusamine has an exceptional I.Q., but Giovanni informs her that no slave of theirs has ever successfully escaped from their castle. After being stripped naked, given a haircut, renamed “Mud” and given a slave dress, Lusamine is escorted to her cell where Cyrus taunts her by saying "Welcome to Our Castle, slave".
Over the next several days, Mud makes acquaintances with a few inmates among them are Lysandre, a vain man who keeps a pet lion, Ghetsis, an American man and the prison librarian, and Archie, a man who paints portraits. However, Mud also encounters a bully named Maxie, who harasses her in the showers and later attacks her in the prison yard with a gun. The guards break up the fight, and both are sent to solitary confinement cells in D block, despite Mud merely acting in self-defense.
Two weeks later, after being released from the brutal, isolated conditions, Mud settles into the routine of being a maid. Ghetsis commands deep respect in the prison yard, sitting high above the other inmates. When Mud approaches, Ghetsis’s friends try to stop him but Ghetsis unexpectedly permits him to sit with him.
