The Conjuring: Last Rites Story Explained: What Is The New Case About?

The Conjuring: Last Rites brings the supernatural investigation franchiseto new ground by adapting the real-world Smurl haunting case, a documented paranormal incident from 1986 in Pennsylvania that became one of Ed and Lorraine Warren’s most infamous investigations.

The film, directed by Michael Chaves and released September 5, 2025, centers on Jack and Janet Smurl, a Pennsylvania family who moved into their dream home only to discover it was plagued by demonic infestation.

Unlike the film’s previous entries, this chapter adds a darker dimension to the Warren family’s story—their daughter Judy Warren becomes directly involved in the investigation, weaving her supernatural abilities into a case that connects back to the very first case the Warrens ever handled.

The new case depicted in the film differs markedly from previous Conjuring entries because it grounds itself explicitly in documented paranormal investigation records. The Smurl family’s experience was considered one of the most disturbing cases the Warrens took on, with activity escalating beyond typical haunting phenomena into territory the paranormal investigators found genuinely alarming.

What Real Case Inspired The Conjuring: Last Rites?

The film draws directly from the Smurl haunting case, a verified investigation conducted by Ed and Lorraine Warren in 1986 at a Pennsylvania family home.

The case gained significant attention because of its intensity and the family’s willingness to speak publicly about their experience, unlike many families who suffered in silence during that era.

The Smurls’ home became a focal point for paranormal activity that went far beyond mysterious noises or fleeting shadows—the family reported escalating violent phenomena that prompted them to seek help from the paranormal investigation community.

The Warren archives contain extensive documentation of the Smurl case, making it one of their most thoroughly recorded investigations. This real-world foundation gives The Conjuring: last Rites a different weight than purely fictional haunted-house narratives.

The film uses this documented history to create legitimacy within the franchise’s universe, positioning the case as a turning point in the Warrens’ career and in Judy Warren’s understanding of her inherited abilities.

The Demonic Activity and House Investigation

The Conjuring: Last Rites portrays the Smurl home as a location where demonic activity didn’t manifest subtly but escalated rapidly and violently.

According to the film’s plot, the family experiences increasingly disturbing supernatural events that move beyond typical poltergeist activity into territory suggesting intelligent, malevolent forces at work. The Warrens arrive to find a situation that challenges even their extensive experience with the supernatural.

One important limitation to acknowledge: while the film dramatizes the Smurl case for narrative impact, some elements are compressed, intensified, or reimagined for cinematic purposes. The real investigation involved months of observation and documentation, whereas the film necessarily condenses these events into a two-hour narrative arc.

Additionally, paranormal investigation remains controversial within mainstream science, with skeptics questioning the methodology and claims made during such investigations. The film doesn’t address these criticisms, instead presenting the supernatural phenomena as genuine threats requiring immediate spiritual intervention.

Judy Warren’s Personal Involvement in the Investigation

A key distinguishing feature of this film is how Judy Warren, the Warrens’ daughter, plays a central role in the investigation rather than serving as a peripheral character. Her psychic abilities, established in previous films, become directly relevant to understanding and combating the demonic presence in the Smurl home.

This represents a significant evolution in how the franchise portrays the next generation of paranormal investigators.

Judy’s involvement adds emotional complexity to the investigation because she’s not simply assisting her parents—she’s confronting the inheritance and weight of her psychic gift. The film uses this dynamic to explore generational themes within the Warren family, showing how abilities and trauma can be passed down.

Her direct encounter with the supernatural forces in the Smurl home forces a confrontation with her own limits and power, making the case personal in ways previous investigations haven’t been for the Warren family.

The Supernatural Mirror Connection to the Warrens’ First Case

A pivotal plot element involves the discovery of a supernatural mirror in the Smurl home’s attic that connects this case to the Warrens’ very first investigation. This narrative device transforms the Smurl case from a standalone investigation into something with deeper mythological significance within the franchise’s universe.

The mirror suggests that the demonic forces plaguing the Smurl home are linked to the original source of the Warrens’ paranormal work.

This connection works as both a storytelling device and a comparison to real paranormal investigation mythology—various cultures have long held beliefs about mirrors as supernatural gateways or dangerous objects. By grounding the film’s plot device in existing cultural beliefs about mirrors and the supernatural, the filmmakers create a sense of logical continuity.

However, this also represents a significant shift in the franchise’s scope, moving from individual hauntings toward a more overarching supernatural mythology that ties multiple cases together across time.

Critical Reception and Audience Response

The Conjuring: Last Rites holds a 57% rating on Rotten Tomatoes based on 190 critics’ reviews, with an average score of 5.8/10, and a 6.2/10 rating on IMDb. This mixed critical reception suggests the film succeeded in some areas while facing criticism in others.

The ratings indicate that while the film has compelling moments and a solid foundation in the real Smurl case, it may have struggled with pacing, character development, or the balance between horror and exposition.

One important limitation worth noting is that critical scores don’t necessarily reflect viewer enjoyment—some audiences connect deeply with specific entries in horror franchises regardless of critical consensus. Additionally, the Conjuring franchise has established a formula that resonates strongly with devoted fans but may feel repetitive to critics.

The case-specific narrative structure that works well for franchise entries designed to capitalize on name recognition may feel constraining to reviewers expecting innovation or deeper exploration of the Smurl family’s actual experience.

How the Case Compares to Previous Conjuring Investigations

The Smurl case stands apart from previous investigations featured in the Conjuring franchise because of its documented real-world basis and the specific documentation available through paranormal investigation archives.

Previous films have adapted verified cases like the Annabelle doll or the Perron family haunting, but the Smurl investigation occurred more recently and involved more extensive public discussion of the events.

Unlike some earlier cases in the franchise, the Smurl haunting involved a family actively seeking public awareness and willing to discuss their experience openly. This meant the real case received media attention and public interest during and after the investigation, contrasting with more obscure historical cases the Warrens investigated that left minimal public record.

The Conjuring Franchise’s Evolution and Real-Case Sourcing

The Conjuring: Last Rites represents a continued commitment by the franchise to base its stories on documented paranormal investigations rather than purely fictional narratives. This grounding in real cases—however dramatized—has become the franchise’s defining characteristic and a key factor in its audience appeal.

Each film positions itself as an account of a real investigation, even while taking significant creative liberties with the actual events.

Moving forward, the franchise’s reliance on the Warren case archives suggests future entries will continue mining documented investigations for material. This approach limits the franchise to cases the Warrens actually documented and investigated, which creates both constraints and legitimacy.

The real-world foundation provides marketing appeal and psychological weight that original fiction wouldn’t offer, but it also means the franchise is inherently tied to the historical record and subject to fact-checking and criticism from those familiar with the actual cases.
