Nabi Project Team is a small-scale secret group secretly operated by the National Police Agency. The group is named after the Hebrew/Arabic word 'Nabi,' meaning 'Prophet,' because they attempt to solve cases by utilizing the skills of Yoo Shi Hyun, who has the ability to sketch drawings of future crime scenes. During a criminal take-down, enthusiastic detective Kang Dong Soo comes across Shi Hyun's sketchbook, which includes a prediction of his fiancée Min Ji Soo's imminent death. His resulting choices indirectly causes multiple disasters, and in the process, an unusually motivated killer is born. As Nabi Project Team pursues him, they encounter an even larger presence behind him pulling the strings.
