Misteryo sa Tuwa

In a peaceful village in the footsteps of Mt. Banahaw, the people were gathered to celebrate a joyous occasion where the villagers and visitors have fun together. On that day, a plane crashes in a nearby area and many people were shocked by the incident. As they discover the remnants, many things and dead passengers were scattered all over the area but everyone saw a lot of items worth of fortune in the area where they stole and retrieve them in order to escape their lives of being poor. On the other hand, the three men Ponsoy, Mesiong, and Jamin steal a suitcase belonging to a dead American passenger from the plane crash which they vow not to report to the authorities.

By the time the authorities knew the knowledge of the suitcase being held by three men, the town mayor Pedro Valle, and his men including Castro, have decided to create necessary measures to suppress the three men and take the suitcase full of money for their personal gains. As the film progresses, the motivations of the characters were exposed one by one as they were continued to be victimized by torture, abuse, and violence as the contingent of soldiers would begin their final assault to kill the pillagers in the mountains as an act of revenge for their violent attack in the village.

On the morning of August 19, 1950, in the village where an army outpost is situated, the three men Ponsoy, Mesiong, and Jamin, along with their families, are on their way home after the baptism of Ponsoy and Ada's son, Tiko. However, as they are almost near to their destination, the military jeep broke down and they were forced to walk on foot to the village. Despite the problem earlier, they are still on their way while the villagers are preparing, and then, they invite Captain Salgado and the people at the camp to the occasion. By the time they arrive, the celebration started to become joyous when the villagers began to enjoy the music, dancing, and the food and drinks they serve.

Suddenly, as the villagers and soldiers enjoy the occasion, a plane crashes into the nearby forest and began running for help. Moments later, they, including the trio, began to check the remains of the plane but instead of searching for survivors and recovering the remains of dead passengers, they start looting whatever they find in the said area, ranging from food to clothes, much to Captain Salgado's dismay and he told them to help with the soldiers instead. While looting, Jamin discovered a black briefcase and it belonged to a dead American passenger nearby. However, Mesiong and Ponsoy believed that the suitcase's contents might be a bomb but when Castro shows up, they leave the area. As they are still looting, a gunshot was heard and the villagers believe that the Huks are back and flee as the soldiers would handle the situation.

At night, the people are happy with their recovered loot from the plane crash. In the case of Mesiong, Jamin, and Ponsoy, the contents of the black briefcase remained mysterious and they still believe that it is a bomb. While no one is watching, they decide to open the briefcase but when it was opened, they became surprised when they discover that the suitcase's contents are no other than money and began to divide every share among each other. On the next day, Pedro Valle, the town mayor, arrives with the soldiers, medical personnel, and two Chinese businessmen although the people thought that the Japanese soldiers are back. In the captain's office, the Chinese businessmen and Mayor Valle informed Captain Salgado about the plane crash, and the suitcase they want to find belonged to an American named Mr. Murphy, the business partner of the former. As the people and personnel help retrieve the dead from the plane crash, they discovered the remains of the American but his briefcase is gone.

Meanwhile, the trio still has no idea what are they going to do with the money they got from the recovered briefcase but Jamin is worried about Castro due to the said thing. While the personnel is leaving for Manila, Castro tells Mayor Valle about the briefcase and the latter made a deal with him. Castro agrees with the deal and admits to him that he was fed up living in the camp. With the worry about the rumors, Mesiong said that the money is ours and he would threaten to kill if someone wants to take back the money they got from the briefcase.

At the town's capital, the townsfolk gathered together at the Anti-Rat Campaign and Mayor Valle is present at the event. As the town secretary began to talk, Mayor Valle began creating a plan on taking back the briefcase with Santos, who has second thoughts about the plan he would do. On the following day, Mayor Valle returns to the camp and talks with the other men, especially Castro about the plan privately. Moments later, Ponsoy, Mesiong, Jamin, and the rest of the loggers return home but at night, things get even worse. A group of men, whose heads were covered with bayong, began terrorizing the village, kidnapping the trio one by one, and when Didong came to check at Mesiong's house, he was shot to death, leading to the panic of the villagers and soldiers. After Santos informed the success to Mayor Valle and started to regret it, the latter told the former that there will be no back-outs in the mission. The following morning, Mayor Valle arrives at the camp furious and asks Captain Salgado where Castro is at.

Within the mountains, the trio was tied up and held hostage by the men led by Castro, whom Captain Salgado noticed his unusual behavior in the previous days. Ponsoy, Mesiong, and Jamin were given torture and interrogation by Castro one by one and he asked where is the briefcase. On the day of Didong's funeral, a group of Hukbalahap arrived in the village but they told them that they were not involved in the crime of kidnapping the trio and Didong's death. Later on, the trio continued to be tortured one by one while their whole bodies (except their heads) were buried in the ground until the captors decided to kidnap Jamin's lover, Ising. At the village, Pinang and Ada began to realize and suspected that Castro was involved in the kidnapping of their husbands while the latter also realized that Mayor Valle is a liar and untrustable.

At night, while Benito is on his way home from fishing, he discovered the location where the captors torture and hostage the trio and he even witnessed the intimidation done by Castro to Ising. After seeing the whole act, he returned home immediately and informed Pinang, Ada, and the rest of his family about it. On the following morning, Mayor Valle and Santos prepare to go to the mountains to retrieve the money while the platoon of soldiers led by Captain Salgado began their last mission (also in the mountains) before they will be reassigned to the town capital. At the same time, Pinang and Ada decided to arm themselves and release their husbands from their captors.

As the wives finally arrived at the location and returned the briefcase, a battle between them followed. As Castro tries to flee with the briefcase, Pinang shoots him in the leg before Ada would finish the job by stabbing him to death. After killing Castro and their fellow captors, the wives and Benito finally freed the trio and Ising and they fled from the area immediately. Moments later, Mayor Valle and Santos finally reached the location, and despite discovering that Castro and the others were killed, they found the briefcase lying on the ground. As Santos gave the briefcase to the mayor, he was shot to death, and as he opens the briefcase, the platoon arrived and a firefight began. The firefight between Mayor Valle and the platoon ended with the former being shot to death and Captain Salgado, who was shot in the arm, discovered the nasty motives of the mayor and his men.

In the following days, the army outpost was dismantled as the personnel moved to the town capital. The film ends with the wedding of Jamin and Ising and the village folk began to enjoy themselves together.
