'Until Dawn' Movie Ending Revealed: The Horror Story Behind the Game-Inspired Film

Understanding the Plot of Until Dawn

Halloween is still months away, but it’s never too early to watch horror movies on Netflix. And clearly, many people are already doing so, given that the 2025 horror movie Until Dawn is one of the streamer’s top 10 trending titles right now. Directed by David F. Sandberg, with a screenplay written by Gary Dauberman and Blair Butler, the film is loosely based on the 2015 interactive drama survival horror game of the same name. While the video game featured A-list voice actors like Rami Malek, the movie cast includes Ella Rubin, Michael Cimino, Odessa A’zion, Ji-young Yoo, Belmont Cameli, and Peter Stormare, the last of whom was also the voice of Dr. Hill in the video game.

The movie plot is quite different from the original game, which can be confusing for fans. If you got lost along the way, don’t worry—this breakdown will help clarify what happened in the Until Dawn movie.

The Journey Begins

Clover (Ella Rubin) is on a journey to retrace the steps of her sister Melanie (Maia Mitchell), who went missing shortly after their mom died. With her is her ex-boyfriend Max (Michael Cimino), their best friends Megan (Ji-young Yoo) and Nina (Odessa A’zion), and Nina’s new boyfriend Abe (Belmont Cameli). The group’s last stop is a gas station where Melanie was last seen one year ago. Clover asks the attendant if he remembers Melanie, but he doesn’t. However, he advises her that many people go missing around an old mining town nearby, Glore Valley.

The friends drive to Glore Valley and take shelter from a rainstorm in the town’s abandoned visitor center. In the center, Abe finds dozens of missing persons posters, including Melanie’s. Nina signs the guestbook, and Clover thinks she hears Melanie calling her from the woods. She attempts to follow, but is pulled back by Max. After signing the guestbook, Nina discovers a page she hadn’t seen before, which shows that Melanie also signed the guestbook, 13 times.

The Time Loop Begins

Abe suddenly sees himself and all the friends’ faces on the missing persons wall. Something is definitely wrong. Soon after, a masked killer breaks into the visitor center and kills every single one of the friends. Wait, so is the movie over? Nope—it’s a time loop!

The night resets, and everyone finds themselves back where they were before: Megan in the bathroom, Abe by the missing persons board, Clover in the woods, and Nina writing in the guest book. The only difference is that Nina can see this is the second time she is writing in the guest book.

However, the night doesn’t repeat the horrors of the previous night. Instead, there are new horrors: Megan is possessed by a demon, and Clover is dragged into a spooky house where a witch tells her she must either “survive the night, or become a part of it.” Everyone dies again, and the time loop resets.

Discovering the Truth

On the next loop, the group goes looking for information and finds an old VHS tape that reveals the gas station attendant is actually a sadistic psychologist named Dr. Hill (Peter Stormare). After a mining accident buried most of the town, Dr. Hill came to Glore Valley to act as a therapist for the survivors. But instead, he performed sick experiments on his already-traumatized patients. One experiment involved trapping a man in a room with no food or water, and over the course of 13 nights, the man turned into a wendigo—a former human that becomes a feral cannibal out of extreme hunger.

Clover speaks to Dr. Hill via an old radio and learns that there is a way out, but one of the friends must die. Clover demands a meeting with Dr. Hill, and he says to find him in the woods. The friends try to stop her from entering this obvious trap, but Abe—clearly thinking Clover could be the one sacrificed—wants to let her go. However, Max, Nina, and Megan insist that unless they are all alive, they should agree to kill themselves and try again. Nina punctuates this point by stabbing Abe. Max goes after Clover, rescues her from a bear trap in the woods, and they are confronted by another wendigo, who Clover recognizes as her sister Mel.

The Final Confrontation

After learning that Megan is already dead, Max and Clover decide to kill themselves and restart the loop. When the loop restarts, Megan is missing. Nina reveals it is the 13th night, based on the log book. It seems no one else survived more than 13 nights without also becoming a monstrous wendigo. The group is shocked to hear this, as they can’t remember what happened all 13 nights. Abe discovers videos he took on his phone that fill in some of the blanks. Basically, a lot of messed up things have happened to them.

Clover realizes it’s too late to rescue her sister, but not too late to rescue her friends. She resolves to go into the tunnel and rescue Megan. The rest of her friends opt to come, too. Friends stick together!

The Wendigos in Until Dawn

Wendigos are a mythological creature from Algonquian folklore, said to be driven by an insatiable hunger to eat human beings. The wendigos in Until Dawn are all other patients who were experimented on and didn’t escape—former humans driven insane who “become the night.” Are they also driven by extreme hunger, the key characteristic of wendigos? Kinda! Sorta! Maybe!

If this doesn’t make sense, you’re not alone. The wendigos were the big bads in the original video game, which took place in a cave and had nothing to do with a psychology experiment. Even though the wendigo thing didn’t fit into the new plot invented for the movie, it seems the filmmakers still wanted to include them. The result is a mishmash of too many monsters, and a plot that doesn’t add up. I mean, is anyone going to explain the time loop?

The Ending Explained

Clover tricks Dr. Hill into drinking some of the contaminated water, causing him to explode. He’s the one who dies, meaning all five friends can escape. And they do! After fighting off the last wendigos, the friends claw their way back above ground, and witness the sun come up. They survived the night, and are free from the time loop.

In the final scene of the movie, we see the TV monitors where Dr. Hill was observing his subjects flicker and change. The screens depict a new location, a snowy log cabin. A different car pulls up to the cabin, suggesting that this is a new location with a tragic backstory, and that these are new traumatized victims showing up for another sick Dr. Hill experiment. We’re not sure how that would work, given that Hill is now dead. But we’re sure if Sony wants to make Until Dawn 2, they will find a way.
