The Housemaid Ending Explained — Who the Real Monster Is, and Why Nina Hired Millie

Nina’s escape plan puts another vulnerable woman in danger. That makes her more complicated than either the unstable wife she pretends to be or a strategist with every outcome under control. Her decision to return for Millie matters as much as her decision to hire her.

Nina’s accusations and changing demands initially make her seem like Millie’s greatest problem. The reversal reveals the abuse behind that performance. Andrew has been locking Nina in the attic and imposing painful punishments for minor supposed failures. She wants him to replace her with Millie so that she can leave with her daughter, Cece. Behaving erratically helps push him toward the younger woman.

Nina chooses Millie knowing she has killed before. Millie’s history makes her attractive to Nina for a reason that goes beyond Andrew’s interest in her: she may resist the violence Nina has endured. Yet hiring someone capable of fighting back is no guarantee that she will survive. Nina gains a route out by exposing someone else to the same abuse.

Money makes that choice uglier. Millie needs a job and a place to live; refusing the household’s demands could cost her both. There is a class tension here that also runs through another recent hit about clawing your way up over somebody else’s body. Nina uses Millie’s limited options, but her later return complicates a reading of her as someone who simply pays to keep her own hands clean.

Millie fights back against Andrew in the attic, stabbing his neck with a cheese knife. She takes his phone and the knife before locking him in. Nina returns to help Millie, but opens the attic and releases Andrew instead. The confrontation reaches the staircase, where Millie pushes him over the railing to his death.

The women then make the death look like an accident while Andrew was changing a lightbulb. Millie leaves before the police arrive. The officer questioning Nina has a personal connection to another woman Andrew harmed, which helps explain her willingness to accept the account. The official story conceals the women’s actions; it does not establish Millie’s self-defense. Nina’s return also changes the moral balance: she risks facing Andrew again after having arranged her escape at Millie’s expense.

At Andrew’s funeral, Nina gives Millie a check for $100,000 and points her toward another housekeeping job. At the interview, the prospective employer’s bruises reveal why Nina recommended her. Millie understands that this woman needs help with an abusive husband and accepts the job. Nina sends her toward a situation she now knows how to recognize.

There is an uneasy possibility in that new job: Millie’s ability to fight back may become something other women rely on. The payment makes the ending more complicated, but it does not prove that every rescue is a killing for hire. Millie now recognizes the sort of danger she failed to see in Andrew. Whether that knowledge offers a way forward or leads her into more violence is the tension the final interview leaves open.

Paul Feig’s adaptation preserves the central reversal of Freida McFadden’s 2022 novel: Nina’s apparent instability conceals Andrew’s abuse. The film changes the mechanics of his death, bringing the conflict out of the attic and onto the staircase. That gives Nina and Millie a shared confrontation, followed by a shared account of what happened.

Nina’s plan succeeds, but its success cannot erase what it costs Millie. Her return prevents that plan from being the whole story of her character. The ending is strongest when those two facts stay in view: Nina exploits another woman’s vulnerability, then comes back rather than leaving her to face Andrew alone.
