Un veterinario sensitivo e un detective uniscono le forze per risolvere casi in una piccola città, ma le loro abilità vengono messe alla prova quando svelano un agghiacciante mistero di serial killer
Bong Ye-bun looks for answers after a meteor shower grants her an unexplainable gift. Moon Jang-yeol struggles to find thrills at his new police station.
After finding herself in another precarious situation, Ye-bun experiences a shocking vision. Jang-yeol scours the town for a potentially exciting case.
In order to break the next big case, Jang-yeol puts Ye-bun through the ringer. But after a strength-building exercise, Ye-bun's power begins to weaken.
One wedding (is announced) and a funeral. Jang-yeol is unexpectedly sensitive to Ye-bun's suffering. Seon-woo's absence is marked as suspicious. Captain Jong-muk and his team are forbidden from investigating the serial killer case and are directed to "protecting people's livelihoods." As one suspect after another is eliminated, Jang-yeol goes back to the beginning and questions all of his conclusions. Ye-bun bursts into his home with a theory that connects all new dots in a terrifying way.
Frustration and grief are running high in Mujin as Detective Jang-yeol and the police track down new leads in a dwindling pool of suspects. Yet another murder is committed, and Jang-yeol is maddened with frustration as the serial killer seems to slip again and again through his fingers. Even so, he makes a shocking discovery and confesses it to Ye-bun. She manages to avoid all efforts to keep her safe, and as Jang-yeol races to her rescue, he may already be too late.
Another death at the hands of the serial killer leaves both Ye-bun and Jang-yeol stunned, grieving, and guilt-ridden in their own ways. The victim provided them with the evidence to convict the killer, but the killer brags they have one shot left, and demands to be released in exchange for the life of the final victim.
Before there can be a happy ending, there must be a rescue, a recapture, some goodbyes, a proposal, some baby talk, a television appearance and an invitation to a date.
