In a quiet, rural village, Jacinta (Maricel Soriano) tends the fields and cares for her mother, Almeda (Armida Siguion-Reyna), a devout and pious woman who has slowly been losing her grip on reality since the death of her husband Arcadio (Robert Arevalo) years earlier. Jacinta is hardworking in the fields and is admired by the women of the village as a dutiful daughter and wife, all while enduring the cold treatment from her husband Peping (Tirso Cruz III).
Across town, Clarita (Snooky Serna)—the younger sister who has not returned home in ten years since leaving to study in Manila—has since married a city lawyer, Joey (Eric Quizon). Clarita returns with Joey to help sort the land titles of Arcadio, and the sisters are briefly reunited, though Clarita feels uneasy about being back. Peping's animosity toward Clarita and Joey stems partly from a prior relationship he once had with Clarita before she left for Manila.
During a conversation between Joey and Almeda, a buried trove of Peping's love letters to Clarita is revealed, sending Almeda into a hysterical state. Jacinta grows furious at Joey for how the letters could complicate things. Peping reveals that he would send letters to Clarita, and Clarita would reply in kind, but she would ultimately pass those letters to Jacinta, who then hides them from both of them. While Jacinta helps with the cleaning, Almeda explains that the letters might soon pass from Joey to Peping, prompting Jacinta to confront Joey about the truth.
At the cemetery where Arcadio is buried, Jacinta recalls how her father first discovered the letters. She reveals that Clarita had been subjected to sexual abuse by Arcadio. Clarita had already fled home, and in a tense confrontation between Jacinta and Arcadio, Jacinta pushes Arcadio, causing him to strike his head on a sharp object and die. Jacinta then confesses to her mother about Clarita's abuse and insists that the family keep the truth hidden, lest Clarita be branded as her father's mistress. Her sanity begins to unravel as she bitterly resents the attention Arcadio had given Clarita, and a fierce brawl erupts in the cemetery before Peping intervenes.
With the family tensions momentarily addressed, Clarita asks Peping to look after her sister as she and Joey prepare to return to Manila, taking Almeda with them so she can seek treatment. Yet Jacinta's mind remains unsettled, recalling the assault and her own disturbing attempts to gain her father’s affection; Arcadio’s reaction—laughter—only deepens her turmoil. Peping catches her crying over the memory and promises to stay by her side. The story closes on a quiet rural afternoon: after the harvest, Peping watches Jacinta dance in the fields, a small sign of fragile grace amid a web of secrets.
