The film opens with a vivid flashback that peels back the troubled past of Kuala](/actor/lolita-rodriguez). She undergoes an abortion performed by an herbolario (traditional folk medicine practitioner) while César](/actor/eddie-garcia) observes. The procedure is successful, but upon seeing the aborted fetus, Kuala is deeply disturbed. In a subsequent scene, she wanders through a scorching grassy plain, her mental state deteriorating as the heat intensifies, driving her toward madness.
In the present day, Kuala, now branded the village idiot, roams her Nueva Ecija town in tattered clothes and unkempt hair. The locals mock and ridicule her, culminating in a cruel act where she is shoved into a watering hole, narrowly escaping drowning.
Bertong Ketong](/actor/mario-ohara), a leper longing for companionship, entices Kuala with a rattle and brings her to his ramshackle home in the cemetery. Junior](/actor/christopher-de-leon) befriends them, defying his father César Blanco, a lawyer and unsuccessful politician.
Junior seeks Berto's counsel about his challenges with his eccentric teacher, Mr. Del Mundo, who harbors a crush on him, and with his girlfriend, Evangeline](/actor/hilda-koronel), who flirted with another during the recent Santacruzan.Consumed by jealousy, Junior leaves the procession and turns to Milagros, who seduces him. Milagros/actor/laurice-guillen) becomes a pivotal figure in this tangled web of loyalties and longing.
The local Asociación de las Damas Cristianas is scandalized to learn that Kuala is pregnant. She is forced into the custody of the devout Lola Jacoba. During a secret visit, Kuala confides in Berto about her unhappiness. Berto shares this with Junior, who vows to help Kuala escape from Lola Jacoba's house and return her to Berto's shack. Realizing the dangers, Berto reluctantly returns her to Lola Jacoba, promising to rescue her after she gives birth.
A few nights later, Kuala goes into labor and makes her way to Berto’s shack. Berto rushes to find a doctor, but when the doctor refuses assistance, Berto takes him hostage, insisting he will not kill him. As they flee, the doctor’s wife screams for help, alerting the townspeople, who pursue them. Before reaching the shack, the doctor manages to escape, prompting a frantic chase. Policemen come to the doctor’s aid and shoot Berto. Junior witnesses this horrific act, collapsing in grief as he holds Berto's lifeless body amid the gathering crowd.
Junior then enters the shack where Kuala has just given birth to a son, although she is weakened by the ordeal. Gaining lucidity, she recognizes Junior and realizes Berto has died. Spotting César in the crowd, she accuses him of killing their child, unveiling his sinister secret. With her final strength, Kuala hands her baby boy to Junior before succumbing.
As Junior leaves the shack, he casts a piercing look at the townspeople, including his parents, Evangeline, and those who have treated him and Berto poorly. He pauses near Berto's corpse, and the onlookers fall into a somber silence. Ultimately, Junior departs the cemetery, carrying Berto and Kuala’s son, determined to forge a new path amidst the shadows of loss and betrayal.
