Sherina tries to leave the observatory through the front door only to discover that it had been locked and the kidnappers were outside.

In Jakarta, Kertarajasa dances with his wife, revealed to be Natasya, and states that he will launch his project the following day once the plantation is legally his. They take documentation connecting the thugs to Kertarajasa and escape to a nearby observatory, where they spend the night. Later, at the kidnappers' hideout, Sherina is able to rescue Sadam while the guards are sleeping. She agrees to this condition and convinces her husband to sell the land to Natasya (Henidar Amroe), who had offered them 2 billion the day before. When the kidnappers try to call Ardiwilaga, they reach his wife ( Ratna Riantiarno) and tell her to prepare a 3 billion rupiah ransom. She discovers that they have been tasked with kidnapping Sadam by a cunning businessman named Kertarajasa (Djaduk Ferianto), who wishes to buy the plantation to complete their development project. She escapes and, when the four kidnappers leave, she follows them. As they gesture for Sherina to get into their car, Sherina hears Sadam's muffled voice from inside its boot telling her to get away. After convincing her that he has found Sadam, they go to a car where another man is waiting. She tries to find her way back to the plantation and stumbles across an adult man. Sherina and Sadam challenge each other to climb the nearby hills and, upon arriving, Sadam attempts to leave Sherina behind. When she accompanies his father to visit the plantation, she discovers that Sadam is Ardiwilaga's son. Sherina cannot accept such treatment and she gathers her classmates in a struggle against Sadam. They often bother children who are weaker. However, she becomes the target of the class bullies, consisting of a boy named Sadam (Derby Romero) and his two friends. In her new environment, she quickly adapts and acquires some new friends. However, Sherina has to leave her friends when her father accepts a job as an agronomist, at a plantation in Lembang owned by Ardiwilaga (Didi Petet). She lives in Jakarta with her parents, the Darmawans (Mathias Muchus and Ucy Nurul). Sherina is a girl who is smart, energetic, and loves to sing.
