Mananabas stars Cesar Montano as a soldier who became a leader of an organized vigilante group in Mindanao that claimed to have superhuman speed and strength when they drink a special kind of oil. Lt. Miguel Marasigan (Cesar Montano) and his men were massacred by their fellow soldiers. Three years later, he and his six men became Mananabas, a vigilante group that has superhuman powers. They attack soldier camps and kill soldiers using their bolo. They later learned that Gen. Tomas Roxas (Spanky Manikan) ordered their massacre. Gen. Roxas has a political ambition once he retires and has a goddaughter news reporter Sabrina (Josephine Canonizado). Meanwhile, only news reporter Teng (Jeffrey Tam) has witnessed the activities of the Mananabas and they allowed him to write a book about them. Miguel had a feud with his member Aragon (Rommel Montano) and they left him alone. Later, Sabrina went to the area to find out the truth about the Mananabas.—Anonymous
