Train S01E01

A closed train station's tracks reveal a chilling discovery of multiple skeletons, yet a surprising turn of events unfolds when one of the deceased individuals appears at the police station alive. As questions arise about the origin of these bodies and the identity of the perpetrator behind the string of murders, the narrative delves into a world fractured by a past homicide that occurred a dozen years earlier. Do Won embarks on a quest for the elusive truth within a parallel universe, shedding light on the divergent paths taken in two starkly contrasting worlds shaped by distinct decisions.
