Princess Qaseh's desire to become the new ruler to develop Kayajaya is hindered by the "Wabak Achum" (Achum Plague). The lives of the people and Qaseh's father are threatened, and Qaseh's qualifications are even questioned by the people. Qaseh tries to get help from the Nusaria government to produce a cure but is stopped by Cik Seri Leeza. Unbeknownst to her, Andika returns and conspires with Raja Sulong to usurp Qaseh's throne.

The people lost confidence in Princess Qaseh as the Achum plague worsened. Qaseh was also accused of needing to get married because a Princess was not fit to rule alone. For the sake of her responsibility for the well-being of the people of Kayajaya, Princess Qaseh asked Cik Sri Lee Za and Pak Hidayat to find her potential husband, while Qaseh continued his efforts to find a cure for the Achum plague. Unexpectedly, a threat from an old enemy appeared on the way to Nusaria.

Princess Qaseh, Laila and Wandika travel through the jungle and ocean, from Kayajaya to Nusaria in an attempt to find a cure for the Achum plague. At the Nusaria palace, they meet Queen Baiduri and her son, the handsome and clever Prince Amal. They agree to go to Kayajaya, but Queen Baiduri turns out to have ulterior motives for Princess Qaseh.

Qaseh tries to help the market traders but Raja Sulong confuses her with various economic theories. Due to pressure from all sides, Qaseh is determined to abdicate her throne as Crown Princess.

News of the failure of the cure spreads, and all of Kayajaya and Nusaria are restless. Trust between Qaseh and Queen Bella is damaged, and Queen Bella takes drastic measures to force Prince Amal to increase efforts to find a cure, and failure will not be tolerated. Princess Amal needs the petals of the Kangkung Sakti Flower (BKS - Bunga Kangkung Sakti), and Qaseh returns to Kayajaya with the hope of bringing BKS from Kayajaya to Nusaria. Then something Qaseh did not expect happened!

The antidote has been successfully produced. However, Queen Baiduri has betrayed Qaseh. Qaseh is looking for a way to rise from this betrayal for the well-being of the people of Nusaria. While Prince Amal and Laila are becoming more aware, something is happening between them. Pak Hidayat and CIk Seri Lee Zha are still trying to reach an agreement to find a candidate for the King Consort for Qaseh.

The competition to find a King of Companions for Qaseh begins. Although Qaseh tries with all his might to resist the competition. Having no choice, Qaseh takes drastic action by joining the competition. Amal is caught between the wishes of Permasirui Baiduri and his own desires. Wan, Amal, Qaseh and several other participants strive to win to achieve their objectives. However, there will only be one winner!
