The film adaptation of Freida McFadden’s bestseller delivers a shocking finale that fundamentally redefines the novel’s core dynamic, transforming a victim’s survival plan into a powerful act of defiant justice and setting the stage for a new franchise.
The final moments of The Housemaid are more than just a plot twist; they are a complete narrative reinvention. While the psychological thriller faithfully adapts Freida McFadden’s 2022 bestseller for its first two acts, the film’s climax makes a deliberate and powerful departure, shifting the agency from the hired help back to the original victim and fundamentally altering the story’s thematic conclusion.
In both versions, the reveal that Nina Winchester (Amanda Seyfried) was the mastermind behind her own ousting is the central pivot. Her supposedly erratic behavior was a calculated performance designed to free herself and her daughter, Cecilia, from the clutches of her sadistic husband, Andrew (Brandon Sklenar). She specifically hired Millie Calloway (Sydney Sweeney) because of Millie’s history of violence—trusting she could defend herself and ultimately eliminate the threat Andrew posed.
The Book’s Gruesome Conclusion: A Test of Endurance
The source material, detailed in the original reporting by USA TODAY, concludes with a grim and psychological form of poetic justice. After Andrew turns his abuse on Millie, she gains the upper hand and locks him in the attic. The novel’s resolution is passive and torturous; Millie slides a pair of pliers under the door and tells Andrew his freedom depends on him pulling out his own teeth.
When Nina returns days later, she finds Andrew’s corpse—bruised, mangled, and missing several teeth. The finale at his funeral, where his mother casually mentions pulling his baby teeth as punishment, completes a cycle of generational abuse. Andrew’s death is a slow, self-inflicted consequence of his own monstrous nature, witnessed by no one. Millie is the instrument, but Nina’s plan relies on Andrew’s inherent weakness and cruelty to execute itself.
The Film’s Active Retribution: Seizing Power
The movie, however, rewrites this ending to be one of direct, confrontational justice. Andrew is still alive when Nina returns to the Winchester mansion. He pleads with her, begging for another chance, effectively trying to gaslight her one final time. Instead of acquiescing or letting Millie finish the job, Nina takes matters into her own hands.
In a moment of cathartic action, she pushes him over a stairwell railing, sending him plummeting to his death. This is no accident; it is a decisive act. Her subsequent cover story—that he fell while changing a lightbulb—is the final piece of her performance, a clever lie that protects her and Millie and allows them to control the narrative completely.
This change is monumental. It transforms Nina from a brilliant strategist who manipulates events from afar into a direct agent of her own liberation. She doesn’t just engineer her escape; she personally delivers the final blow to her oppressor. This aligns thematically with the film’s stronger emphasis on the bond between Nina and Millie, which is explored more visually as seen in the official promotional materials from the film’s distributor. It becomes a story of solidarity and women actively dismantling the structure of their abuse, rather than one simply outsmarting it.
Franchise Implications: The Door is Wide Open for a Sequel
This altered ending dovetails perfectly into the film’s post-credits scene, which is a direct lift from McFadden’s 2023 sequel novel, The Housemaid’s Secret. Millie is hired by another wealthy woman who claims to be in a similar situation and says she came “highly recommended” by Nina.
The film’s conclusion makes this next chapter more logical. Nina isn’t just a survivor; she’s now a veteran of a successful operation. Her recommendation carries the weight of someone who has seen the plan through to its ultimate, violent conclusion and emerged unscathed. It suggests she and Millie could become partners in a much larger, clandestine enterprise—a twist far more compelling than the book’s more isolated ending.
This analysis confirms the film’s ending isn’t merely a change for shock value. It’s a deliberate narrative choice that empowers its central characters more fully and creates a stronger launchpad for a potential film series. By having Nina take direct action, the story becomes less about surviving a nightmare and more about ending one definitively.
