Outpost (2022) Ending Explained – Reality vs. Hallucination
Movie Details: Director: Joe Lo Truglio | Runtime: 1h 24m | Release Date: 2023 | Star Rating: 2.5/5 Stars
Welcome to Knockout Horror. We recently reviewed the horror-thriller Outpost (2022). It wasn’t great, and the storytelling was a little scattered, leaving many viewers confused about what was real and what was a hallucination.
Rather than summarising the entire film, I am going to cut straight to the chase and answer the burning questions left by the chaotic ending. Yes, Kate really did those things, and no, Bertha wasn’t real. Let’s break it down.
⚠️ Warning: Major spoilers follow below.
The Ending in Brief
The TL;DR: Kate suffers a complete psychotic break due to CPTSD and isolation. She murders two hikers, her neighbour Reggie, and Ranger Dan, believing them to be threats. She is eventually caught by Earl and Nickie, who lock her in the fire tower as police sirens approach.
Was Bertha real? No. Bertha (the hiker Kate befriended) was a hallucination based on photographs of Reggie’s late wife that she had seen in his house. Kate projected her own anti-male sentiments onto this imaginary figure to justify her violence.
Did Kate eat people? Yes. The “rabbit” she thought she was eating with Bertha was actually the limb of one of the hikers she murdered. Earl finds the charred remains near the end.
Did Mike attack her in the tower? No. Mike (her abusive ex) appearing in the tower was a hallucination. However, it is strongly implied that Kate may have killed the real Mike before the events of the movie even began.

Outpost (2023) Ending Explained
To understand the ending, we have to, in effect, diagnose the protagonist. Kate (Beth Dover) isn’t just “stressed”; she is in the grip of a severe mental collapse that is the root cause of everything that happens.
What Was Wrong With Kate?
Kate is likely suffering from CPTSD (Complex Post-Traumatic Stress Disorder) combined with psychosis. Unlike standard PTSD, which is often triggered by a single event, CPTSD stems from prolonged trauma – in Kate’s case, childhood sexual abuse by her uncle and severe physical abuse by her ex-partner, Mike.
This trauma manifests as hyper-vigilance, paranoia, and hallucinations. She takes the job at the fire tower to escape people, believing solitude will heal her. Instead, the isolation acts as a bit of an incubator for her psychosis, detaching her completely from reality. With nobody around to help ground her, she slips further and further away into psychosis.
Context: What is CPTSD?
Kate is portrayed as suffering from Complex Post-Traumatic Stress Disorder (CPTSD). Unlike standard PTSD, which is often triggered by a single traumatic event, CPTSD results from prolonged, repeated trauma – such as the long-term abuse Kate suffered from her uncle and her ex-partner.
Key Symptoms:
- Emotional Dysregulation: Sudden, uncontrollable outbursts of rage or panic.
- Distrust & Isolation: A belief that nowhere is safe and no one can be trusted.
- Distorted Perception: Seeing the perpetrator in others (e.g. Kate believing Reggie is an abuser).
- Dissociation: Detaching from reality, which can escalate into psychosis in severe, untreated cases.
The Hallucinations vs. Reality
A huge chunk of what we see in the movie isn’t actually real. Kate is deep in delusion, paranoia, and psychosis which is causing her to hallucinate frequently. Her perception of the world is completely muddled. Here is the breakdown of who existed and who didn’t.
- Bertha (The Hiker): NOT REAL. Bertha (Becky Ann Baker) was a manifestation of Kate’s fractured mind. It is implied she based this persona on photos of Reggie’s deceased wife she saw in his house. Bertha served as an “enabler,” validating Kate’s violent impulses and telling her that “all men are abusive.”
- Reggie’s Wife: REAL (but dead). Reggie frequently spoke about his late wife. Kate’s hallucination of Bertha painted Reggie as a wife-beater who killed her, but in reality, Reggie was a kind, grieving widower. Kate simply projected her own trauma onto him.
- The Uncle in the Toilet: NOT REAL. The naked man Kate sees in the outhouse is a flashback hallucination of her abusive uncle.
- Mike in the Tower: NOT REAL. The scene where Mike attacks her in the tower is a delusion. However, Mike was a real person in her past.
The Grim Twist: Kate was a Cannibal
One of the most disturbing, and nasty, reveals happens when Earl and Nickie arrive at the tower. They find a charred human limb.
Remember the scene where Kate and “Bertha” are happily eating a rabbit by the fire? That wasn’t a rabbit. Kate had murdered a male hiker, butchered him, and was eating his flesh. Her mind disguised the gruesome act as a bonding moment with her imaginary friend.
Who Did Kate Actually Kill?
By the time the credits roll, Kate has racked up a pretty significant body count. Here is the confirmed kill list:
- The Two Hikers: Early in the film, Kate “shoots rabbits.” In reality, she was shooting the two hikers she saw earlier. She killed one, chased down the other, and stored one body in the septic tank of the toilet (which Nickie finds at the end).
- Ranger Dan: When Earl suspects something is wrong, he sends Ranger Dan to check on Reggie. Kate intercepts him and murders him with an axe (or shoots him, the chaos implies a brutal end either way).
- Reggie: Kate sets a bear trap in Reggie’s garden. When he returns home and steps in it, she shoots him. She killed him because her hallucinations convinced her he was an abuser, despite him being innocent.
- Mike (Maybe): It is heavily implied that Kate may have killed Mike before the movie even started. She tells Nickie that Mike “hasn’t been seen for days.” Given her state, it is likely she killed him in self-defence (or paranoia) and fled to the tower to hide.
That’s a pretty decent number of victims considering she was working in an isolated fire tower with barely anyone around. Well done Kate!
Reality Check: The “Hollywood” PTSD Trope
It is important to note that Outpost relies on a highly sensationalised, “Hollywood” depiction of mental illness that prioritises shock value over accuracy.
The film leans into the harmful trope that trauma inevitably turns victims into violent maniacs. In reality, studies consistently show that people suffering from PTSD and CPTSD are far more likely to be victims of violence than perpetrators of it.
Kate’s transformation into a serial killer is a slasher movie device, not a realistic portrayal of trauma. Viewers should view this strictly as a horror fantasy, rather than a reflection of real-world mental health struggles.
Was It The Solitude That Broke Her?
It is easy to look at Outpost as a standard “cabin fever” movie where isolation drives a person mad, similar to The Shining or… Well, Cabin Fever. However, looking at the evidence, it is highly likely that Kate had already entered a state of psychosis before she even walked up the steps to the tower.
Kate arrives at the mountain already paranoid, jittery, and arguably dissociative. The biggest clue lies in her backstory with Mike. She tells Nickie that Mike “hasn’t been seen for days.” When you combine this with her extreme volatility from minute one, it implies that the traumatic event, likely her killing Mike, had already happened.
We could infer that she had already snapped, killing Mike, and bailing to somewhere remote either in an attempt to get away from the legal implications or to be away from people to prevent more murders.
She didn’t go to the tower to heal; she went there to hide. The solitude didn’t cause her insanity; it simply removed the social masks she was using to hide it, allowing her violent delusions to take the wheel completely.
Frequently Asked Questions
Why was Kate suffering from CPTSD?
Kate had suffered a childhood of abuse at the hands of her uncle. As an adult, she found herself in a supposedly abusive relationship with boyfriend Mike. This left her badly traumatised.
Did Reggie kill his wife?
No. Reggie was a decent man. Kate’s hallucination (Bertha) told her that Reggie was a killer to justify Kate’s hatred of men. There is no evidence Reggie was anything but a loving husband.
Why did Kate stop doing her job?
As her psychosis deepened, she covered the windows of the tower to stop people “looking in.” She abandoned her post to live in Reggie’s house (while he was away), leaving it covered in filth and human waste, signalling her total detachment from social norms.
What happens to Kate at the end?
Earl fights Kate and is wounded. Nickie (Kate’s friend) intervenes, stopping Earl from killing her. They lock Kate inside the fire tower. As the camera pulls away, Kate is screaming, trapped in the very place she went to find peace, awaiting the police.
Final Thoughts: Trauma Porn or Character Study?
Outpost attempts to walk the fine line between psychological thriller and slasher, but it frequently trips over its own ambitions. It presents a messy exploration of trauma that, unfortunately, leans heavily into the harmful trope of “mental illness equals violence.” Instead of a nuanced look at CPTSD, we get a protagonist whose trauma transforms her into a cartoonish villain. I really hate this kind of stuff.
While it aims for the complexity of a character study, it ultimately devolves into a slasher where the killer is the protagonist. It is confusing, potentially stigmatising, and a bit irresponsible in its depiction of abuse survivors. However, if you are just looking for chaos, unreliable narration, and bloodshed, there’s a fair bit of that. It’s a shame the lead up is so damn dull.
