So here’s the deal. Zach Cregger’s new horror movie Weapons hit theaters, and right from the poster, it’s teasing you with one super creepy line:
“Last night, at 2:17 a.m., every kid in Mrs. Gandy’s class woke up, left their beds, walked out the front door… and never came back.”
Pretty unsettling, right?
If you’re curious about what actually happened — but maybe not ready to sit through two hours of slow-burn horror — here’s the whole story, told straight, like you’re hearing it from a friend.
The Disappearance That Shook the Town
The Weapons ending mystery kicks off almost instantly. Mrs. Justine Gandy (Julia Garner) is a middle school teacher. One night, every single student in her class disappears — except one boy, Alex (Cary Christopher). No one knows why.
A month passes. The school reopens. But now, parents are furious. They think Justine knows more than she’s saying. She gets threatening notes, angry confrontations — the works.
The People Pulled Into It
The story doesn’t follow just one person. It splits into a few connected threads:
- Justine — scared, stressed, and reconnecting with her ex, Paul (Alden Ehrenreich), who’s now a cop.
- Archer Graff (Josh Brolin) — a father whose son, Matthew, is among the missing. He’s angry at Justine but also running his own investigation because the police aren’t making progress.
- Andrew (Benedict Wong) — the school principal, who checks in on Alex’s home after Justine raises concerns, only to find a strange old woman there.
Aunt Gladys and the Creepy Truth
That strange old woman? She’s Aunt Gladys (Amy Madigan). And she’s the key to the weapons ending.
Gladys moved in with Alex’s family when she got sick. But she’s not just a sick aunt — she’s a witch. And she’s been using dark rituals to paralyze Alex’s parents. They can’t speak. They can’t move. She’s draining their energy to heal herself.
Then she ropes Alex into helping her. She tells him to bring her something personal from each kid in his class. He steals their name tags from the school cubbies.
With those, she casts a spell. That’s why the kids disappeared — they were pulled, almost like sleepwalking, straight to her house in the middle of the night. She hides them in the basement and feeds off their life force too.
Why It’s Called Weapons
Here’s the even darker part of the weapons ending setup: Gladys can hypnotize people and give them one job — kill a specific person.
It’s exactly what the title means. She turns people into “weapons.”
One night, Archer is confronting Justine at a gas station. Out of nowhere, a hypnotized Andrew charges at her, trying to strangle her. Archer steps in, fights him off, but Andrew runs into the road and gets hit by a car. Dead on the spot.
This moment changes things — Archer stops treating Justine as the enemy, and they decide to work together.
Following the Trail
The two start mapping where the kids were last seen. Every line points back to Alex’s house.
When they get there, things go south fast. Paul, now hypnotized, is waiting — along with Anthony, a local addict Paul had argued with earlier. Both men attack.
Inside, Alex is hiding from his own parents, who are also hypnotized and trying to kill him.
The Basement Showdown
Archer heads down to the basement to find the missing kids. Instead, he finds Gladys — and she turns him into her next weapon. She orders him to kill Justine.
At the same time, Alex is cornered. Justine’s choking. Archer’s eyes are blank. It’s about to be game over.
The Turning Point in the Weapons Ending
And then — Alex makes his move. He casts his own spell.
This time, instead of obeying Gladys, all 17 missing kids turn on her. They chase her down in a frenzy, finally catching her and literally tearing her apart.
It’s brutal. Head, arms, legs — gone.
The moment she dies, every spell breaks. Archer drops his grip. Alex’s parents snap back to normal. Paul and Anthony stop their attack. The kids in the basement are freed.
What Happens After
The weapons ending doesn’t just stop there — it gives you the fallout:
- Alex’s parents are sent to a psychiatric hospital to recover.
- Alex goes to live with a kind aunt.
- All the missing kids go home. Some don’t speak for months. A few slowly start talking again before the year ends, showing just how deep the trauma went.
Why the Weapons Ending Works
The weapons ending hits because it’s not the cops or the adults who save the day. It’s the victims — the kids — who take down the villain.
It’s a mix of supernatural horror and revenge story. The slow build pays off in a wild, chaotic final act. And while Gladys is gone, the idea that someone like her could exist out there still lingers.

Final Thoughts
The weapons ending explains exactly why those 17 kids walked into the night — they were being controlled by a witch, used as her energy source and as living weapons.
It’s creepy, violent, and leaves you uneasy in the best way. And honestly? That’s exactly what a horror ending should do.
