Nujum Pak Belalang

Belalang encounters Badan and Nyawa after they steal two cows and frightens them away, reclaiming the livestock. He brings the cows home and reports the theft to Pak Belalang, who panics and insists they must be returned to the rightful owners. Belalang then proposes going to the mayor's house to identify the owners, with Pak Belalang posing as a psychic who can locate the cows.

Belalang's plan is to visit the mayor to identify the cows' owners. Pak Belalang pretends to be a psychic capable of locating the missing cattle. The ruse succeeds, and they are rewarded for recovering the livestock.

Thieves strike again, this time at the royal palace, stealing valuables. Sultan Shahrul Nizam announces a reward for anyone who can recover the items. The mayor, impressed by Pak Belalang’s supposed psychic abilities, brings him to the palace, but Pak Belalang falters at bluffing and the Sultan gives him three days to recover the items or face execution.

Desperate, Pak Belalang hides in a cave at Bukit Tunggal as Belalang suggested. There he overhears Badan and Nyawa dividing the stolen loot. Disguised as a hunched-back elder, he frightens them away and recovers the gold chest.

Belalang is captured by palace officials and brought before the Sultan. When the Sultan threatens him, Pak Belalang suddenly appears, claiming to have found the stolen items. He then orders the palace officials to crawl on all fours to retrieve the chest, which amuses the Sultan and confirms the recovery.

Grateful for recovering the loot, the Sultan appoints Pak Belalang as the National Healer. During the appointment ceremony, the princess Puteri Sri Bujur Sirih fakes a faint to meet him, and they secretly confess their love.

The Kingdom of Masai arrives with a fleet, proposing a war of wits between their National Healer and Pak Belalang. They threaten to take Masai's land unless Pak Belalang wins; if he loses, the Kingdom of Beringin Rendang will be ceded.

Refusing to participate, Pak Belalang sends Belalang to secure a boat to escape. Belalang overhears Masai’s National Healer giving away the answers to the riddles while hiding in their boat.

On the next day, Pak Belalang uses the overheard knowledge to answer all the questions correctly and secures victory for his kingdom. The Masai are stunned as their strategy fails and the crowd cheers the winning tactic.

During a demanded bonus challenge, Pak Belalang cries out his son's name in a moment of despair. A real locust appears, and the timing reveals the correct answer, saving the kingdom.

Badan and Nyawa, now allied with Masai, kidnap the princess after casting a spell over the palace. Pak Belalang is threatened with death if he cannot locate her.

Pak Belalang's blessed water reveals the princess’s location and implicates the conspirators. He rescues the princess and foils their plans.

Grateful, the Sultan orders Pak Belalang and the princess to marry. The royal court celebrates the triumph as the heroes are honored and the realm is safe.

The film ends with a humorous exchange between Pak Belalang and his son Belalang, who laments not having his own room. His father teases him and they share a lighthearted moment about family quirks.
