The Complete Plot of A24’s ‘Backrooms’ Has Apparently Leaked Online — And It’s More Unsettling Than You’d Think

The internet has been collectively spiraling ever since A24 confirmed that the viral creepypasta phenomenon was getting a full theatrical adaptation. With the ‘Backrooms‘ movie hitting theaters at the end of May, the drip feed of leaked details, on-set discoveries, and trailer reveals has painted a surprisingly clear picture of what the story actually looks like, and horror fans are not sleeping.

What makes this whole situation genuinely compelling is the pedigree behind it. At just 20 years old, Kane Parsons is making his directorial debut with A24, becoming the youngest person ever to lead a production for the acclaimed independent studio. That alone would be a remarkable story, but the plot details now circulating online suggest he has built something far more ambitious than a simple internet-to-screen translation.

The Backrooms Movie Plot Details That Have Leaked

The core story structure has come together through a combination of official synopses, trailer reveals, and genuine on-set leaks. The film introduces Clark, who owns a pirate-themed furniture store called Cap’n Clark’s Ottoman Empire, and during a sale at the store, a strange doorway opens in the basement. Clark investigates and discovers an alternate dimension, the Backrooms, and quickly becomes obsessed with the place, exploring it every night.

Clark tries to explain his discovery to his therapist, who does not believe him. Later, Clark tasks two companions with coming with him as proof, and after they seemingly go missing, the story ends with the therapist entering the Backrooms herself. That dual-protagonist structure gives the film something most horror movies of this type never bother with: an emotional anchor for audiences who might otherwise feel distanced by the concept.

The film centers on two people, Clark played by Chiwetel Ejiofor, a furniture store owner who disappears randomly one day, and his therapist Dr. Mary Kline played by Renate Reinsve, who comes to the store to search for him after he vanishes. Unfortunately for Mary, she becomes as lost in the Backrooms as he is, searching for a way out and a way back to reality. The screenplay is credited to Will Soodik, who completed revisions on an original draft.

What the On-Set Leaks Actually Confirmed

Several fans who lived or worked in areas where filming was taking place captured information during production in 2025. Among the most significant early leaks was a driver’s license photo posted and later deleted by the director himself on his Discord server, which appeared to show that the main female character would be named Charlotte Marie.

Another leak came from a fan who photographed actor Mark Duplass on set before his casting had been publicly announced. From the same source came a wider photo of the set with the crew at work.

Several fans analyzed the number plates on the cars visible on set and concluded the movie would be set around 1990, a detail that was later confirmed by the director himself at the beginning of 2026. The period setting and British Columbia location add a layer of temporal isolation that feels wholly appropriate for this kind of story.

The film is set in the 1990s, echoing the aesthetic of Parsons’ original YouTube series which followed a fictional research institute, Async, as it studied the mysterious alternate dimension known as the Backrooms or simply the Complex. Whether the feature film ties directly into the Async mythology from the web series remains officially unconfirmed, though the thematic and visual connections are clearly deliberate.

Kane Parsons and the Liminal Horror Vision Behind the Film

The creative approach Parsons has taken is one of the most talked-about elements of the project in horror circles. The latest trailer emphasizes the movie’s mix of traditional filmmaking techniques and found footage, as Clark enlists the help of people he knows to explore the Backrooms. The focus is split between his own investigation and that of Mary, who appears to be looking for him. The trailer also reveals the first time multiple regular people have gone into the Backrooms at once.

Fans praised the trailer for staying faithful to the source material, with eagle-eyed viewers noting that a specific shot recreated the same Backrooms room from the original 4chan post. One commenter summed up the collective mood with a simple assessment, saying the trailer was pitch perfect from the Backrooms environment to the characters, and that Parsons has it.

Critics who attended an early premiere described the film as wholly unique and original, a horror film that freaks you out and creeps you out while luring you deeper into its eerie liminal nightmare, the kind of movie that gets under your skin and stays there. Others called it easily the best creepypasta adaptation yet, while praising the performances of both Reinsve and Ejiofor.

The A24 Release and What Comes Next

The film has an estimated budget of around ten million dollars and is being positioned as a horror tentpole for A24 as the summer box office season kicks into high gear. That is a lean budget by blockbuster standards but generous for the genre, and it suggests the studio has real commercial ambitions for the project beyond a limited art-house run.

The film stars Academy Award nominees Chiwetel Ejiofor and Renate Reinsve alongside Mark Duplass, Finn Bennett, Lukita Maxwell, and Avan Jogia. Producers include Shawn Levy and James Wan, bringing the creative minds behind Stranger Things and The Conjuring universe into the fold. That combination of new and established talent signals that A24 is treating this as something more than a cult curiosity.

Parsons’ original short film, which launched the entire cultural phenomenon, has accumulated nearly 190 million views on YouTube. Converting even a fraction of that audience into ticket buyers would make ‘Backrooms’ a genuine box office story. The film runs at 105 minutes and carries a May 29 release date, landing in one of the more competitive windows of the summer season.

Whether Clark’s obsession with the endless yellow halls proves as contagious for general audiences as it was for the internet faithful is the real question, so if you have been following every trailer frame and leaked detail, tell us what part of the plot has you most intrigued or most worried about what Parsons might actually be hiding.
