Arya and her family occupy a house left by her parents who have been empty for eight years, since Arya's father died. Since moving to the house, Srimaya said that Nawangsih often had nightmares and woke up. And one day Kinar also found Nawangsih going down to the warehouse in the basement of their dark and dirty house making Kinar drive Nawangsih out of the warehouse. The next day when Nawangsih was tutoring with Donny, the private teacher who taught him, suddenly Nawangsih was seized like seeing something scary. Donny reported what happened to Nawangsih

Donny came to teach Nawangsih. The antique lights next to Nawangsih caught Donny's attention. And when Arya told Donny that he hadn't been able to pay the tuition fee, Donny offered to sell the antique lamp. Although Kinar forbade Arya from selling the antique lights, Arya and Donny managed to bring the antique lamp to Donny's boarding house. The boarding house owner who has a relationship between the buyer of the antic goods, is very and sure to sell at a high price. Suddenly the electricity went out, but the antique lights even lit up.

Kinar is disappointed with Arya's actions while selling the lights which makes Nawangsih very sad. Then, as seen Nawangsih walked towards the warehouse, Kinar followed. Kinar and Arya are very surprised, and makes Nawangsih even more angry at his father seeing Arya approaching the antique lamp. When Donny came to escort Srimaya and told of a strange incident in his boarding room, Arya was very surprised and told him that the antique lamp was in the warehouse of their house.

Arya & Kinar are very confused when they find out Nawangsih disappeared. Kinar went quietly to look for Nawangsih. Arya, assisted by her house manager, Tumin, searched around their housing and did not find Nawangsih. Tumin took the initiative to ask Mpok Hindun for help, who was known as someone who had supernatural powers. While Arya was worried that there would be no news from Kinar, and waited for Kinar to come home, Arya found a letter with a worn-out kerta in the drawer of her desk which was the former work desk of her father.

Nawangsih's disappearance is still a mystery, Srimaya also got a terror which he believed came from an antique lamp, as if following him. At night Kinar could not sleep, and saw an envelope that turned out to be the letter Arya found in her desk drawer. Secretly Kinar read the letter and was very surprised when reading it, there was the name Nawangsih in the letter. That's when the room door slowly opened, making Kinar very scared.

Arya and Kinar are very happy to find Nawangsih has returned home. But that was not what Srimaya felt, which felt his parents loved Nawangsih more. After returning from school, Srimaya ventured anger at Nawangsih and accused him of terrorizing Donny. When going to bed, suddenly Nawangsih experienced a very severe seizure, and his gaze to the corner of the ceiling of his room seemed to be fixed on something

Donny asked Mpok Hindun for help so that he could take the antique lamp and promise the proceeds from the sale. Donny was unsuccessful, even a hard fist floated into Donny's face as Arya caught him in the living room of Arya's house. Arya could not hold back her anger, resulting in what Arya and Kinar had covered up could no longer be kept secret. While Nawangsih increasingly heard clearly his name was always called by a figure that was not seen by ordinary people, and gave him directions to a place that revealed the mystery that had existed.

Kinar who was cleaning up suddenly felt a great contraction. The situation was precarious when Kinar contracted even more while Nawangsih asked his father to deliver him to a place where he got a guide to reveal the mystery that had not been revealed. When Arya escorted Nawangsih, Donny returned to Arya's house and forcibly seized the antique lamp. He pushed Kinar to fall and bleeding.

At that time Nawangsih finally managed to uncover a hidden mystery, What mystery has been hidden? Why did Nawangsih reveal the mystery? Where did the sound from Nawangsih come from?
