After executing her judgment, she condemns their souls to Hell. However, her life takes an unexpected turn when she encounters Han Da-on, a detective with a warm and gentle demeanor. As a detective, his mind is sharp and he has a keen sense of observation. Despite his outward kindness, Han Da-on harbors deep, unseen pain. Their meeting sets off a series of events that profoundly alters both of their lives.
