25-year-old Audrey accidentally travels from 2025 back to a small town in Tennessee in 1985. At that time, the future clean energy giant Ethan Cross is still a mechanic covered in oil, working late into the night on blueprints; the future seven-time Grammy rock legend Jude Hart is still a struggling singer, singing alone to empty chairs in a deserted bar. With her knowledge of the future, Audrey becomes a guide at key moments in their lives—helping Ethan improve engine airflow and helping Jude avoid career-ruining contracts. As she witnesses the rise of these two geniuses, her unconditional trust and companionship draw them in. The story breaks the traditional 'choose one' romantic cliché, ultimately leading the three of them to achieve ultimate harmony and mutual growth in their careers, destinies, and souls, walking side by side towards a legendary future.
