Hae-jun, a man with a cynical demeanor, works as an anchor at a news station.

However, his world is turned upside down when he unexpectedly comes across a time machine, something he never thought could exist. Yoon-young leads an ordinary life as an editor at a publishing company until she discovers her mother's lifeless body by a riverside. One day, her life takes a drastic turn when she gets struck by an invisible car near the same riverside and wakes up in the year 1987.
