The Mummy 4 – The Book of the Dead Reopens (2026) unfolds several years after the O’Connell family believed they had finally escaped the shadows of ancient curses. Rick and Evelyn have settled into a quieter life in London, while their son Alex has become a respected archaeologist in his own right. The story begins when Alex uncovers a sealed chamber beneath the ruins of Abydos, a site long rumored to house forbidden scriptures predating even Imhotep. Against his better judgment, Alex removes a relic encrusted with unfamiliar hieroglyphs—an action that unknowingly reopens the dormant Book of the Dead.

Soon after the discovery, a series of disturbing omens sweep across Egypt: sandstorms rise without warning, the Nile briefly runs black, and whispers in an ancient tongue echo through abandoned temples. Evelyn begins to translate inscriptions related to Alex’s find and realizes the book was not merely a tool of resurrection—it was a prison. Within its pages lies the essence of Neferaset, a sorceress queen whose power once rivaled the gods. Sealed away by the priests of Ra, she has waited millennia for a moment of weakness to return.

As Neferaset’s spirit takes form, she begins gathering the lost fragments of her soul scattered across Egypt’s sacred sites. Each fragment she reclaims unleashes catastrophes that ripple across the modern world, drawing the attention of Rick and Evelyn, who are pulled back into a fight they thought was over. Their journey reunites them with Jonathan, still chasing fortune and charm, who becomes an unexpected key to locating the final missing piece Neferaset needs to fully return.

Driven by guilt, Alex ventures deeper into the desert with a team of explorers, only to discover that Neferaset seeks more than resurrection—she intends to rewrite history itself, restoring an age when dark magic ruled unchecked. The O’Connells must race against time to stop her, battling cursed guardians, ancient traps, and illusions meant to separate them permanently.

In the film’s climax, the family faces Neferaset inside a colossal inverted pyramid buried beneath the shifting sands. With the book’s power spiraling out of control, Evelyn realizes that the only way to imprison the sorceress again is to sacrifice the relic itself and sever its connection to the mortal world.

The story closes with the O’Connells watching the desert swallow the last remnants of the ancient structure. Though victorious, they sense that history never truly stays buried—and some legends continue to breathe beneath the sands.
