Elang Darat, who leads a gang of robbers continuously harasses the village of Kresek. To overcome the security threat, the head of the village calls for assistance from a detective, R. Parlan. During a raid, Parlan is injured, and is nursed by Rukmini, the village head’s daughter. Their closeness prompts jealousy in Gunawi, the adopted son of the village-head. Later, it is revealed that Gunawi is the son of R. Bardan, Parlan’s father. Parlan then must face Gunawi because he is actually the one that people call Elang Darat.
