The final act reveals the dark truth of the Winchester household. Andrew locks Millie in the attic as punishment for breaking his mother's antique china plate. While trapped, Millie learns the full extent of Andrew's abuse.
Nina had previously been subjected to the same attic confinement, forced to pull out her own hair when her blonde roots showed, and was framed for mental instability and trying to drown Cece when she refused to have his child. Realizing Andrew's pattern, Nina deliberately hired Millie, knowing Millie matched Andrew's exact type, to set a trap and escape her abusive marriage. As punishment for the plate, Andrew commands Millie to cut her stomach with a china shard for each of the twenty-one pieces.
Millie plays along until she falls asleep, then wakes up and stabs Andrew with a knife supplied by Nina. Millie locks him inside the attic and forces him to extract one of his own front teeth with pliers by threatening to smash more heirloom china and set the attic on fire. Millie reveals her ten-year prison sentence was served for beating her best friend's rapist to death.
When Nina returns with Cece, she sneaks into the attic to help. Andrew attacks both women, but Millie escapes his grasp. When Andrew attempts to kill Nina, Millie returns and shoves him into the stairwell, sending him plunging to his death.
To cover up the murder, Nina drops a lightbulb to stage a DIY accident and summons Enzo to clean the scene. Officer Jessica Connors remains suspicious of their statement, but ultimately classifies the death as a freak accident because her own sister was once traumatized by Andrew. Following the funeral, Nina hands Millie one hundred thousand dollars and departs for California with Cece.
In the final scenes, Nina refers Millie's services to her friend Lisa. When Lisa hints that her husband is abusive, Millie happily accepts the position, suggesting she will continue using her unique skills to rescue victims.
