What Happened to Monday Explained and The Real Villain

Hey there everyone! Welcome back to Movie Soapbox, the little corner of the internet that only you and I and that guy sleeping in the corner over there know about. This is the place where we find underappreciated films, dig into the ones that actually tried something, and make sense of them together. Today we are doing a deep dive on What Happened to Monday, a movie so politically sharp and structurally weird that it feels like it survived no fewer than six rounds of notes from people who had never once in their lives asked a hard question about anything.

Before we get into it, here is the trailer, so you know what we are dealing with.

Alright. If you have not seen this film yet, close this tab, go watch it on Netflix, come back. My review is four words: it is worth it. Everything past this paragraph is a full-contact spoiler zone, and I mean everything, the ending, the twist, what Monday actually did and why, all of it. You have been briefed.

Now. Let us talk about what this film actually is, beneath the premise.

The World of What Happened to Monday Movie

The world of What Happened to Monday is built on a very specific kind of policy horror. Overpopulation triggers a food crisis, the food crisis triggers a genetic modification boom, the modification boom causes a surge in multiple births, the surge makes the original problem geometrically worse, and into that feedback loop steps Dr. Cayman, played by Glenn Close with the flat affect of someone who genuinely believes every terrible thing she is doing. She heads the Child Allocation Bureau, which has instituted the One Child One Earth act. Every sibling beyond the first gets frozen in cryo-sleep, allegedly, until population levels stabilize. A woman named Karen Settman has seven daughters, dies in childbirth, and leaves her father Terrence, played by Willem Dafoe, to raise them in a locked apartment under a single shared identity. Each girl gets a day of the week. One goes out per day. The collective is Karen Settman. The fiction holds for decades.

Then Monday does not come home.

What the film understands, and what a lesser version of this premise would have fumbled completely, is that the survival architecture Terrence built was always going to crack at exactly the point where one of the sisters wanted something the collective could not have. A private life. A relationship. A pregnancy. The system does not break because the government finds them. It breaks from inside, because the prison was built by the people who loved them.

This is the kind of film that a certain tier of international co-production can actually pull off, and it is worth understanding why. Director Tommy Wirkola was working with a budget and a cast configuration, Noomi Rapace carrying essentially seven roles, Glenn Close providing the marquee institutional weight, Willem Dafoe doing the quiet heavy lifting, that sits in a very specific zone below the threshold where a major studio would have insisted on a franchise architecture and above the threshold where this gets made for nothing and disappears. At that budget tier, in that co-production structure, a director often retains just enough creative control to keep the ugly politics in, to leave the third act ambiguous where a domestic studio release would have forced a cleaner resolution, and to let the villain be right about the wrong things in ways that are genuinely uncomfortable. You can feel in the final cut that nobody forced this into a redemption arc for the bureau. That is not nothing. Films like this, with this much going on thematically, routinely get their edges sanded off in post when someone upstream gets nervous about the audience response in Cleveland. This one kept them.

Let us walk through what actually happens, day by day, because the structure of this film is doing real work and the source material you found online probably just called it confusing without explaining why it is confusing in a specific and intentional way.

The Days of the Week of What Happened to Monday

Monday. She meets Jerry, a colleague who signals he knows something is off. She gives the presentation they have all been building toward, the promotion they have been collectively working for, and she does not come home. The other six assume she went to celebrate.

Tuesday. She goes looking. She traces Monday to Harry’s bar, where there was an argument. She gets picked up by the Child Allocation Bureau and brought before Cayman. Guards come to the apartment using Tuesday’s eyeball scan. What follows is the film’s best action sequence, each sister fighting in a way that reflects her specific personality, the health obsessive, the skater, the number cruncher, all of it readable in how they move. Sunday dies in this fight. The apartment is compromised.

Wednesday. She goes to Jerry’s, and he greets her with, hello Karen, you are cutting it close, which is not about the sisters at all. He has found a 407c transfer contract. Monday has been moving money into Cayman’s campaign fund. Jerry wants Karen to back off the promotion or he goes public. Wednesday extracts herself through some fingerprint misdirection, gets the contract to her sisters, and then makes a rooftop jump to escape and gets shot by Joe, Cayman’s field agent. Wednesday is gone.

Thursday. She and Friday use a mirrored wristband, lifted by Saturday from the CAB agent Monday had been seeing privately, a relationship none of them knew about, to access the processing center’s video feed. They find Monday in cell C34. Saturday is killed at the agent’s apartment. Friday stays behind in the apartment to sync the family photos to a broadcast system, then destroys herself and the apartment to cover Thursday’s exit. That is four sisters dead. Thursday gets Adrian, the agent, to carry her into the bureau in a body bag. Inside, they discover what the cryo-chambers actually are. Incinerators. Every child who was ever remanded to cryo-sleep is dead. Has been dead.

And then Thursday finds Tuesday in Monday’s cell, alive, missing one eye.

Because Cayman kept a hostage. Because Monday knew. Monday has been negotiating, with Cayman, using the money she transferred, to be the only Karen Settman. To have the life. The relationship. The pregnancy she is already carrying. She has been paying for the right to be singular while her sisters were hunted.

Thursday and Monday meet in a bathroom at Cayman’s fundraiser gala. Monday has the gun from the apartment safe. The confrontation is a physical fight between the same actress playing two people who grew up in the same room and hate each other in ways that only people who shared everything can manage. Thursday survives. Tuesday plays the incinerator footage at the gala. Cayman is exposed. Joe shoots Monday. Adrian shoots Joe. Monday dies asking Thursday to protect the twins she is carrying.

Tuesday and Thursday walk out with two babies and the regime is finished.

Now let us untangle the things the movie leaves deliberately murky, because there is a difference between the things it does not explain and the things it does not explain on purpose.

The Outstanding Questions of the Movie What Happened to Monday

Why couldn’t Terrence just forge single-child bands for all of them? The film implies he can duplicate and mask data but cannot generate fraudulent origin records without triggering a verification audit. It is a thin explanation and the movie knows it is thin, which is why it does not dwell on it. You are meant to accept the premise and move into what it costs these women, not interrogate the biometric infrastructure.

Why do the sisters keep asking about themselves in public? This is the film’s most legitimate structural crack. Over and over, a sister will walk into a bar and ask what Karen Settman did there yesterday, which is the kind of question that should immediately flag as bizarre. The film leans on the idea that the name Karen Settman is so mundane and ubiquitous that nobody thinks twice, but it is a stretch and there is no real way around it.

Why take the dead sisters to the incinerators? Because from the CAB’s operational perspective, a dead body and a live body going into the same machine produces the same result with no additional paperwork. The incinerators are not a secret chamber, they are just the standard processing unit, which is its own specific horror.

On the theories. There are two real camps on what this film is fundamentally about.

The Theories Trying to Explain What Happened to Monday

Theory one: this is a film about institutional evil and the courage it takes to expose it. Cayman is the villain, the CAB is the apparatus, and the six sisters who die are martyrs to a just cause. Monday is a tragic figure who broke under the weight of an impossible life, but the system that created that impossibility is the real subject. The twins at the end are the future the regime was trying to prevent.

Theory two: this is a film about what family does to people. Terrence Settman built a prison and called it love. He hacked off parts of his granddaughters’ bodies to enforce collective discipline. He raised seven people who could not have private selves and then acted surprised when the one who found a way to have one became monstrous in the process. The CAB is the external pressure, but Monday is what happens when you build a human being who has never once been allowed to be singular and then she finally is. Cayman is almost beside the point. Terrence made Monday.

Moviesoapbox’s Preferred Theory for What Happened to Monday

My read is theory two, and I will tell you exactly why. The title of this film is doing something most people walk past. You read What Happened to Monday and you think: she is missing, that is the mystery. But the movie is asking a different question entirely. What happened to Monday as a person. What made her. The answer is Terrence, the chopped fingers, the shared name, the decades of enforced erasure. Glenn Close gives you a villain you can point at, and she is good at it, but the film’s actual indictment is of the grandfather who thought keeping them alive was the same thing as letting them live. Monday did a monstrous thing. She did it because she was made by someone who never once considered what it would cost her to always be everyone and never be herself. That is the real film. Everything else is the action scaffolding around it.

What you are watching is a Netflix acquisition that could very easily have been reduced to its elevator pitch, seven women, one body, one week, and nothing else. It was not. It kept the eugenics horror, it kept the ambivalent ending, it kept the question of whether the survivors are right to forgive Monday open and genuinely uncomfortable. Films at this budget level, with this premise, in this release window, do not usually come out the other side with their teeth intact. This one did. That is worth something. Not everything, the logical gaps are real and the gala bathroom scene is a fantasy of empty square footage, but something. Find the films that kept their teeth. That is always the job.
