S Line follows Hyeon-heup, a woman who has possessed a strange ability since birth: she can see red “S Lines” that link people together in ways others cannot understand. She keeps this gift secret until a pair of special glasses allows others to perceive the lines as well. As attention grows around the phenomenon, Hyeon-heup becomes the focus of investigative forces and shadowy figures seeking to exploit the S Lines for their own gain. What begins as a unique visual power turns into a deep mystery involving human psychology, fate, and hidden connections between past traumas and present danger. Through suspense, supernatural intrigue, and emotional character dynamics, S Line challenges viewers to question what they see versus what’s really real.
