“When Mirim turns twenty-six, she will go blind.” The prophecy of ‘Grandma Baek’ shakes Mirim’s family to its core. To escape this ominous fate, the family decides to take in a surrogate to bear the curse on their behalf. Thus, Jinkoo is brought into the household. At first, the ritual seems to succeed. Mirim’s eyesight remains intact, but Jinkoo pays a tragic price, losing his life in an accident. Years pass, and Mirim lives burdened by guilt and longing for Jinkoo. One day, a pilgrim arrives at their old family home, claiming to bridge the boundary between the living and the dead—through whom Mirim hopes to reunite with Jinkoo.
