Lee Cronin's The Mummy (2026): Ending Explained

In Aswan, a woman known only as the Magician and her family keep a sarcophagus in a basement beneath their home. When it is opened, the mummy inside awakens and kills her husband with a hook through the jaw. In Cairo, American journalist Charlie Cannon and his wife Larissa live with their children, including young Katie, who plays with a neighbor girl named Layla. The Magician uses Layla to groom Katie with sweets, then conjures a scarab from a nectarine, chants a spell, and abducts the unconscious girl. A sandstorm blocks Charlie's pursuit. Local police suspect the parents, and Detective Dalia Zaki is left with no clues. The family returns to America. Eight years later, Katie is found in a sarcophagus after a plane crash near the Magician's estate. Frail, pale, and changed, she is brought home to Albuquerque. Katie's behavior grows violent and supernatural. She attacks Larissa's mother Carmen, sheds skin and blood, and gradually turns her siblings against the family. Charlie finds ancient writing grafted into Katie's skin. A hieroglyphics expert translates it as a spell used to bind a demon that sows discord and murder inside households. Katie kills Carmen, staging it to look like suicide, and later feeds on her body inside the coffin at the funeral. Charlie decodes Morse code Katie taps out with her jaw, proof that the real Katie is still conscious inside. It leads Zaki to Layla.

Zaki tracks Layla's family to Egypt, shoots the Magician's cult into submission, and gets Layla to switch sides. Layla shows her a home video revealing the truth: the Magician's family has held a generations-old duty to imprison the demon inside a chosen innocent child, sealed in a wrapped sarcophagus. They moved the demon out of the mummy in the opening scene and into Katie. When flooding threatened their valley, they tried to fly the sarcophagus out by plane, and the demon caused the crash, freeing itself.

Back in New Mexico, the finale erupts. Katie's brother Seb, already under her influence, frees her. Carmen's corpse rises and attacks Zaki, who is flown in with the evidence and ends up with a scorpion tail bursting through her throat. Charlie is beaten by Katie in her room. He tells Zaki to recite the spell from the video and transfer the demon into him instead. The spell works: Katie vomits the demon out, and it possesses Charlie. It is a sacrifice for a father who spent eight years convinced he failed to protect his child.

The final scenes show the aftermath. Katie, scarred but healing, communicates with her father through Morse code from the basement, which is now covered in the binding spell. Then Larissa and Zaki take a wrapped, restrained Charlie to the prison where the Magician is held. Larissa sedates the Magician, and they repeat the ritual, moving the demon from Charlie into her. Charlie is freed. The Magician becomes the new vessel, trapped inside the cell.

Grim, gory, and vengeful, with a cathartic final scene that turns the victim's family into the ones holding the leash.

Survives, freed of the demon but scarred.

Survives after temporarily becoming the demon's host, freed in the prison scene.

Survives.

Survive; both fall under the demon's influence but recover with Katie.

Survives, even after the scorpion attack, and helps with the final ritual.

Killed by Katie, then briefly reanimated during the finale.

Captured and imprisoned, then becomes the demon's new host.

Survives, having turned against her mother; her later fate is not shown.

Killed by the mummy in the opening scene.

There isn't just one. The demon inside the original sarcophagus, Katie as its vessel, Charlie wrapped for the final ritual, and the Magician as the last host all fill the role in turn.

The Magician explains that a pure, innocent child is the best vessel, which is why her family targeted Katie and, by implication, other children before her.

She survives and is healing with her siblings, but she is visibly scarred, and the film treats her recovery as an ongoing process rather than a clean reset.

Layla turns on her mother and helps Zaki, but the film never shows where she ends up afterward, which leaves her open as a possible future keeper of the ritual.

Their valley was due to flood, so they needed to relocate it. The choice of a plane, rather than a truck, is one of the film's unanswered plot questions.

It is contained for now, but the film shows the demon needs a human host that eventually breaks down, so the risk of it escaping again is built into the premise.
