Alice

In the year 2050, a mechanism called Alice allows people to travel back in time, primarily to find closure through seeing deceased loved ones. However, after a rumor about the end of time travel begins to circulate, Alice agents Yoon Tae Yi (Kim Hee Sun) and Yoo Min Hyuk (Kwak Si Yang) are sent to 1992 to find The Book of Prophecy. When they arrive, Tae Yi learns that she’s pregnant with Min Hyuk’s child, and she decides to keep the baby despite potential health risks, remaining in 1992 and adopting the name Park Sun Young. Unfortunately, Sun Young is later murdered, and in 2020, her son Park Jin Gyeom (Joo Won) seeks out her killer. But during his search, he happens to meet a genius physicist named Tae Yi – who looks just like his mother.
