Cindy Campbell, grieving the tragic death of her husband Tom Ryan in a bizarre
traffic accident, seeks a fresh start. She takes a job as a live-in caretaker for an elderly, immobile woman named Mrs. Norris living in a notoriously haunted, isolated house. Shortly after moving in, Cindy meets her new neighbor, Tom Ryan, a divorced crane operator struggling to reconnect with his estranged children, Robbie and Rachel. Cindy and Tom experience an instant romantic attraction, bonding over their shared eccentricities and the looming sense of dread that pervades
the neighborhood.Simultaneously, a global threat emerges as mysterious, gigantic extraterrestrial tripods—dubbed the "Tri-Pods"—suddenly invade Earth, ruthlessly vaporizing humanity. Seeking refuge from the apocalyptic chaos, Cindy and Tom flee together, navigating a war-torn landscape. Along the way, they become separated. Cindy stumbles upon a bizarre, isolated Japanese village while searching for answers, where she discovers that the haunting in Mrs. Norris’s house is somehow connected to the alien invasion. She learns about a vengeful phantom boy trapped within the cursed dwelling, whose lingering rage is acting as a beacon, guiding the destructive alien ships directly to Earth.Driven by a desperate motivation to save humanity and protect Tom, Cindy races back to the haunted house. She must confront the supernatural entity and decipher a cryptic message left behind. Meanwhile, Tom and his children are captured by the invading aliens and taken to a bizarre processing facility where humanity is being harvested. However, Tom manages to inspire a minor rebellion among the captives, leveraging his everyman charm and physical clumsiness to disrupt the alien machinery.Back at the house, Cindy successfully uncovers the source of the curse, realizing she must appease the ghost by engaging in a ridiculously ill-advised, fast-paced game of Simon Says to soothe his spectral trauma. Her successful completion of the game neutralizes the paranormal signal, instantly short-circuiting the Tri-Pods and causing them to self-destruct mid-air, saving the planet from total annihilation.Following the global victory, Cindy and Tom reunite on a television talk show to share their harrowing survival story. Overcome with sudden emotion, Tom goes on a bizarrely enthusiastic, furniture-destroying rant to declare his passionate love for Cindy, mimicking a famous real-life television meltdown. Despite the overwhelming absurdity of his public declaration, Cindy is deeply touched by his dramatic devotion, and the couple happily embraces, securing their bizarre romance amidst the ruins of a saved world.
