Shin Ha-Ri has lived and died seven times, but she doesn't know it. Since childhood, she has been haunted by terrifying nightmares-flashes of her own past lives, each ending in a gruesome death. In every dream, she desperately tries to reach for someone's hand, but she never sees his face. Her parents have sought doctors, shamans, and spiritual healers, but nothing has helped. She has learned to live with the nightmares, though a deep fear lingers in her heart.
On the other side of the city, Kang Ji-Hoon-a handsome and cold-hearted business tycoon-struggles with his own dreams. Night after night, he witnesses a woman calling out to him, drowning in blood, fire, or darkness. But no matter how hard he tries, he can never see her face. He dismisses them as hallucinations and relies on sleeping pills to escape his torment.
Fate brings them together in the most unexpected way, triggering a series of events that will unravel the mystery of their past lives. As they begin to recall their tragic fates one by one, they must race against time to break the curse that has doomed them to love and lose each other for centuries.
