Meu Prap Maha Hien

Sergeant Pee is a young police sergeant at the Crime Suppression Division whose ultimate dream is to be a hero and help people, just like his late father who died during a drug raid. However, Sergeant Pee never seems to reach his dream due to his own extreme clumsiness. He is truly considered the weak link of his division.
A mysterious missing person case occurs with zero evidence. Captain Oat, a pompous and bossy superior who dislikes Pee because of his poor performance record, orders Pee to provide security and act as an escort for Nammon, a newly graduated female forensic expert, as she searches for evidence. However, instead of helping, Pee ends up causing more trouble and annoyance for Nammon, making their first time working together far from smooth.
Besides Pee and Nammon, who are investigating the trace-less disappearance, there is another person relentlessly tailing the case. She is Tookta, a charming and determined female journalist who specializes in deep-dive investigative news under the motto "What Tookta knows, the world knows." She constantly hangs around the police station, using her charm to coax secrets out of young and old officers alike. Her most frequent victim is Captain Oat himself.
Feeling frustrated with his job, Pee returns to the station only to receive a letter from his village headman: "Uncle Kongkaow has passed away. Return immediately to sort out the inheritance." Uncle Kongkaow was Pee's only living relative, and just thinking about him gives Pee the creeps. Back when Pee was a child, his uncle practiced dark magic, raised spirits, and often locked Pee up in the cemetery or put him inside graves—terrifying experiences that left deep traumatic scars on Pee’s childhood.
Pee returns for his uncle’s funeral and receives a very surprising inheritance: a rusty old tin box. Inside are a rubber band, a bottle of nam man phrai (corpse oil), a cursed clay doll, and a small chicken bone. To Pee, this looks like trash rather than an inheritance, so he abandons the tin box at the temple before leaving. Before heading back, Pee visits the venerable Luang Pu (an old monk), who tells him, "You must carry on your uncle’s mission!!" and leaves him with a profound quote: "The more power you hold, the more goodness you must practice in return." Confused and still annoyed, Pee returns to Bangkok. Unbeknownst to him, all of his movements are being watched by a mysterious man filled with vengeance.
Meanwhile, Tookta uses her charms to persuade Captain Oat into ordering Pee to take her along to cover the case. Reluctantly, Pee has to obey.
Back in Bangkok, Pee continues the missing person case by taking Nammon to the scene of the disappearance. Suddenly, Pee feels a dark energy he has never sensed before. Pee and Nammon disagree on many things. Captain Oat specifically ordered Pee to take very good care of Nammon because she is the daughter of a high-ranking official, and Oat hopes to woo her for the sake of his own career! Determined to solve the case and prove Nammon wrong, Pee comes up with a plan, but Nammon shoots it down completely. Eventually, Pee gives in and lets Nammon lead. Her plan is to act as bait to lure the criminal out! But first, Pee has to get rid of Tookta by tricking her into covering a fake news story elsewhere.
The plan seems to work: the kidnapper appears, but ends up grabbing Pee instead of Nammon! Nammon tries her hardest to save Pee and makes a shocking discovery—these criminals aren't normal humans; they are zombies! The shock causes her to faint.
Pee is chased by the zombies and gets cornered. Desperately searching for a weapon, he magically finds the rusty old tin box he had left at the temple in his pocket. He throws the box in panic! Suddenly, a miracle occurs. The rubber band transforms into an elastic Preta (a tall hungry ghost). The corpse oil bottle turns into a female water spirit (controlling water). The cursed doll becomes a fiery ghost child (controlling fire). And the small chicken bone turns into a Krahang ghost with a rice pestle (controlling wind).
The four ghosts use their magical powers to fight off the zombie horde. Just then, Tookta arrives, manages to snap a picture of the zombies, but has her camera destroyed and is chased away. The zombies are defeated by the four ghosts and retreat.
The ghosts are thrilled to meet Pee, but the feeling isn't mutual. The ghosts explain that they were raised by Uncle Kongkaow, who assigned them a final mission: they must help Pee do good deeds so they can accumulate enough merit to be reincarnated into a better life. Furthermore, if Pee refuses to take care of them, the mysterious man—who is currently plotting a massive evil scheme—will capture them and force them to become his evil minions, dooming them to suffer in hell forever.
Pee remembers Luang Pu's words: "Carry on your uncle's mission," and "The more power you hold, the more goodness you must practice in return." He finally understands that the four ghosts are the special power he must use to protect the good and suppress the wicked. Pee makes a pact with the four ghosts: he will use their powers to help humans and stop evil, but everything must be kept strictly secret.
Pee wakes Nammon up. She is still terrified by the zombies, but Pee lies and tells her they were just crazy people whom he already chased away. Nammon is still suspicious but accepts it for now. Pee takes Nammon and the four ghosts back to the station.
Meanwhile, Tookta senses that a massive story and strange events are about to unfold, which could make her a top-tier journalist. She decides to stick close to Pee and Nammon at all times.
The three of them have no idea about the chaotic, X-Files-level supernatural cases waiting for them, or who the mysterious man controlling the zombies trying to capture Pee really is. Many questions await them. Find out the answers in the action-comedy drama Mue Prab Maha Hian (The Super Spooky Ghostbuster).
