In 2045, Hill Valley has become a high-tech city, but time itself faces an unprecedented threat. Marty McFly receives a mysterious signal from his future self—a desperate warning about a “Time Rift” that’s rapidly expanding, threatening to erase all timelines and plunge the present into chaos. Doc Brown suddenly returns with a next-generation DeLorean powered by quantum time energy. Together with Clara—Doc’s genius granddaughter—they embark on a mission to stop this disaster. They uncover a new enemy: a descendant of Biff Tannen, who’s using artificial intelligence to manipulate events in the past, present, and future to crown himself the “Time Emperor.” Their adventure takes them through critical moments in history—from 1955, where hidden secrets first emerge, to 1985, where forgotten memories are awakened, and finally to 2099, in a climactic battle at the “Library of Time”—the vault that holds humanity’s entire collective memory. But can they stop time from collapsing before the countdown reaches zero? And what if the price to pay means sacrificing the legendary DeLorean forever—ending all time travel once and for all?
