The 2025 reimagining of The Mummy Returns begins with a chilling discovery in the shifting sands of Egypt, where an ancient burial chamber—long hidden beneath collapsed ruins—is unearthed during a research expedition. Inside lies a forgotten relic connected to the Scorpion King, a relic said to awaken a long-dormant power capable of bending the world to its will. When the artifact is transported to London for study, strange seismic disturbances erupt across the globe, hinting that something ancient has begun to stir.

Rick and Evelyn O’Connell, now retired from treasure-hunting, are reluctantly pulled back into danger when their son Alex becomes entangled in the mystery. After touching the relic, Alex begins to experience haunting visions of the Scorpion King’s return and a prophecy foretelling the collapse of human civilization. Fearing the pattern resembles the events they survived years earlier, the family reunites to stop history from repeating itself.

Meanwhile, a secret cult devoted to ancient gods seeks to resurrect the Scorpion King, believing that his rule will restore “divine order” to the modern world. Their rituals unleash a swarm of supernatural forces—sandstorms shaped like monstrous creatures, armies of undead warriors, and ghostly guardians awakened from their millennia-long slumber. The O’Connells once again find themselves racing against time, pursued across deserts and cities by foes both mortal and immortal.

As Alex’s visions intensify, he realizes he is connected to the relic through an ancient lineage he never knew existed. The power threatens to consume him, pulling him closer to the Scorpion King’s will. Rick, torn between protecting his son and destroying the artifact, struggles with the possibility that Alex may become the key to the Scorpion King’s resurrection.

The story reaches its climax within a colossal underground temple revealed beneath the shifting sands of the Sahara. There, the cult completes the final steps of the ritual just as the O’Connells arrive. A battle erupts between human determination and supernatural wrath, with Alex fighting to resist the force trying to claim him.

In the end, the family’s unity becomes their greatest weapon. Alex shatters the relic, severing the link to the Scorpion King and causing the temple to collapse as its ancient power implodes. Though victorious, the O’Connells understand that the ancient world never truly sleeps—and that some secrets buried in the desert are meant to remain untouched.
