Years after the defeat of Anubis and the restoration of peace in Egypt, Rick and Evelyn O’Connell believe their days of adventure are finally behind them. The Mummy 4: The Book of the Dead Reopens begins in London, where the O’Connells live a quiet life surrounded by their archaeological findings. Their son, Alex, now a renowned Egyptologist, discovers an ancient scroll hidden inside a relic from Thebes. The writing reveals a chilling prophecy: “When the words of the dead are spoken again, darkness shall rise to claim the living.” Against his better judgment, Alex begins to translate it, unknowingly awakening an evil more powerful than any his family has faced before.
Strange omens soon follow—the skies over Egypt darken, the Nile turns to dust, and whispers of the dead echo through forgotten tombs. The scroll leads to the rediscovery of the Book of the Dead, believed to have been destroyed years ago. But this time, the book is not merely an artifact; it has transformed into a living force, capable of reshaping reality itself. Drawn by visions of ancient gods and endless power, Alex sets out to find the book, unaware that dark forces are already hunting it.
A new enemy emerges in the form of Queen Neferkara, an ancient sorceress once betrayed by Imhotep. Resurrected by the power of the book, she seeks to use its magic to rewrite history and rule both the world of the living and the underworld. Her army of reanimated priests spreads terror across the desert, forcing Rick and Evelyn to take up their old weapons once again. The family reunites with familiar allies, including Jonathan, whose greed and humor bring both trouble and courage to their quest.
Their journey takes them across haunted ruins, cursed oases, and lost temples beneath the sands. Each step reveals more about the true nature of the Book of the Dead: it is not just a record of souls, but a doorway—one that can be opened from either side. As the boundaries between life and death weaken, cities fall under waves of sand and shadow. Humanity’s survival depends on sealing the book forever, but doing so may demand the ultimate sacrifice.
In the final confrontation at the Valley of Kings, Alex faces Neferkara within a collapsing temple as the spirits of Egypt rise from their tombs. With Evelyn’s knowledge and Rick’s bravery, they manage to turn the book’s power against its mistress, trapping her spirit inside for eternity. But as the sands settle, the book vanishes once more, leaving behind only a whisper carried by the wind.
The Mummy 4: The Book of the Dead Reopens ends with the O’Connells standing beneath a blood-red sunset, unsure if their battle is truly over. The last scene shows the book resting beneath shifting sands, its golden cover glowing faintly—as if waiting for the next soul bold enough to open it again.
