Soon, she discovers that the house hides a secret and is haunted by the legendary sundel balong, a vengeful spirit with a strange anatomical anomaly.

Then Yati runs away with the fortune and the child of her affair. Neneng, who stays, commits suicide. Her father realises his mistake and reconciles with Sumiati. Rachmat has also come back for Mira.
