You think you know your partner. You’ve shared meals, maybe a mortgage, and definitely a few secrets. But Watch What Keeps You Alive—a 2018 survival thriller directed by Colin Minihan—takes that cozy domestic security and shreds it with a hunting knife. It’s a movie that doesn't just ask if you can survive the wilderness; it asks if you can survive the person sleeping right next to you. Honestly, it’s one of those films that stays in your teeth long after the credits roll because it taps into a very specific, very human fear: being hunted by someone who knows your every weakness.
Movies about couples in the woods are a dime a dozen. We've seen The Strangers. We've seen Eden Lake. But Minihan, who previously gave us the cult hit Grave Encounters, flips the script by making the threat internal. There are no masked slashers or supernatural entities lurking in the pines of British Columbia where this was filmed. The monster is Jackie. Or, more accurately, the monster is the person Jackie is pretending not to be.
The Brutal Simplicity of the Plot
The premise is deceptively lean. Jules (played by Brittany Allen) and Jackie (Hannah Emily Anderson) head to a remote family cabin to celebrate their one-year anniversary. It’s beautiful. It’s quiet. It’s idyllic until a childhood friend of Jackie’s drops by and refers to her as "Megan." That one tiny slip—a name that doesn’t belong—is the first thread to pull. From there, the sweater doesn't just unravel; it gets soaked in blood.
What makes people want to watch What Keeps You Alive isn't just the gore, though there is plenty of that. It’s the pacing. About twenty minutes in, there is a physical shift in the movie. A literal push. Without spoiling the exact moment for those three people who haven't seen it yet, the film transitions from a romantic drama into a relentless, high-stakes game of cat and mouse.
Hannah Emily Anderson’s performance is nothing short of chilling. She plays Jackie with this terrifying, vacant pragmatism. She isn't a screaming maniac. She’s a math teacher. She’s calculated. She’s efficient. Watching her hum a tune while cleaning a rifle after trying to murder her wife is a level of "nope" that most horror films fail to achieve.
Why the Psychology Hits Harder Than the Violence
Most horror movies rely on "The Other." The monster is something outside of us—a ghost, a demon, a guy in a hockey mask. This movie is different. It’s about the betrayal of the intimate.

Psychologically, the film explores "masking." It suggests that some people are just empty vessels who mimic human emotion to get by. Jackie doesn't hate Jules. That’s the scariest part. She just finds her inconvenient to her current goals. When you watch What Keeps You Alive, you’re forced to confront the idea that sociopathy can look like a loving marriage for 364 days out of the year.
Brittany Allen, who also composed the film’s haunting score, delivers a performance that is raw and exhausting. You feel her confusion. You feel the moment her heart breaks, which happens way before her bones do. Her character, Jules, isn't a "final girl" in the traditional sense. She’s a woman who is grieving the loss of her relationship while simultaneously trying to keep her carotid artery intact.
The cinematography by David Schuurman uses the vastness of the Canadian wilderness to create a sense of claustrophobia. It’s a paradox. You have miles of forest, yet there’s nowhere to hide because the person chasing you knows exactly how you think. The use of blacklight in one particular sequence is a visual masterclass, turning a dark cabin into a neon-stained nightmare that highlights the hidden "stains" of Jackie’s past.
Technical Brilliance and the "Beethoven" Motif
Music plays a massive role here. Not just the score, but the diegetic music within the world. Jackie plays the piano. She plays Beethoven’s Moonlight Sonata. It’s a cliché in thrillers for a villain to like classical music, but here it feels earned. It’s part of her "human" costume. It’s the high-culture veneer she uses to hide the fact that she is essentially a shark in a knit sweater.
The sound design is intentionally sparse. You hear the crunch of gravel. The heavy breathing. The terrifyingly calm click of a camera shutter.

There’s a specific scene involving a boat in the middle of a lake that is a masterclass in tension. It’s broad daylight. There’s nowhere to run. The water is still. In that moment, the film moves away from being a "slasher" and becomes a psychological chess match. You aren't just watching a fight; you're watching a negotiation for a life.
Real-World Production Tidbits
Interestingly, Brittany Allen and Colin Minihan were a real-life couple during the filming. That adds a weird, meta layer to the tension on screen. Can you imagine directing your partner to crawl through the dirt while being hunted? It’s a testament to their professional relationship that the film feels so authentically visceral.
The movie was shot on a relatively low budget, which actually works in its favor. It forces the story to rely on the actors rather than CGI spectacles. It’s intimate. It’s dirty. It feels like something that could actually happen in a cabin three hours outside of Vancouver.
Common Misconceptions About the Ending
People talk about the ending a lot. Some find it polarizing. Without giving away the final beat, some viewers think Jules makes "dumb" horror movie choices. But if you really watch What Keeps You Alive through the lens of trauma, her choices make sense. She isn't a soldier. She’s a person in shock.
The film challenges the "Final Girl" trope by making the survival feel like a pyrrhic victory. Even if you get away, how do you ever trust another human being again? That’s the lingering horror. The physical wounds might heal, but the psychological reality that your soulmate tried to toss you off a cliff stays forever.

Actionable Insights for Horror Fans
If you're planning to sit down and watch this, or if you're a filmmaker looking to learn from it, here are the key takeaways from the What Keeps You Alive experience:
- Pay attention to the background. Minihan loves to hide Jackie in the frame. Sometimes she’s just standing there, watching, while Jules thinks she’s safe. It’s a lesson in "negative space" and how to build dread without jump scares.
- Study the color palette. Notice how the colors shift from warm, sunset ambers in the beginning to cold, clinical blues and harsh blacks as the night wears on.
- Watch the "rehearsal" scenes. There are moments where Jackie practices her reactions in the mirror. It’s a terrifying look at how predators simulate empathy.
- Listen to the silence. The film uses the absence of sound to make the sudden bursts of violence feel more jarring. If you’re watching at home, turn off the lights and keep the volume high to catch the subtle foley work.
Final Perspective on Survival
Ultimately, this movie isn't just about surviving the woods. It’s a dark exploration of the "Sunken Cost Fallacy" in relationships. Jules keeps hoping the "real" Jackie will come back, even when the real Jackie is standing right in front of her with a crossbow.
If you want a film that respects your intelligence and doesn't lean on tired tropes, you need to see this. It’s mean. It’s lean. It’s a reminder that the most dangerous thing in the world isn't a monster in the closet—it's the person holding the door open for you.
To get the most out of the experience, pair this with other "subversion" horrors like The Invitation (2015) or Hunter Hunter (2020). These films form a sort of "trust no one" trilogy that highlights the shift in modern horror toward grounded, human-centric threats. Stop looking for ghosts and start looking at the people you invite into your life. That’s where the real danger lives.
Next Steps for the Viewer:
- Check your local streaming listings (it frequently hops between Shudder, Netflix, and IFC Midnight).
- Look for the "making of" featurettes if you can find the Blu-ray; Brittany Allen’s process for composing the score while acting is fascinating.
- Observe the "Megan" subplot carefully on a second viewing; the clues are scattered much earlier than the first reveal suggests.
