Yu-Jung is in the hospital recovering from her third suicide attempt when she receives a life-changing visit. Her no-nonsense aunt appears by her side and suggests Yu-Jung accompany her on a charitable visit to death row. There she meets Yun-Soo, a convicted murderer who will soon be put to death. Through weekly, hour-long meetings, Yu-Jung and Yun-Soo slowly reveal to each other the dark secrets of their pasts and the hidden traumas that have shaped their lives.

Amid the tremors of political revolution, Jung Yoon, a highly literate, twenty-something woman, recounts her tragic personal history. When Yoon receives a distressing phone call from her ex-boyfriend after eight years of separation, memories of a tumultuous youth begin to resurface. She revisits the death of her beloved mother, the strong bond with her now-dying former college professor, the excitement of her first love, and the friendships forged out of a shared sense of isolation and grief.
