The film starts in a drought-ridden area of Metro Manila, where a service van meant for a country club nearly collides with a group of locals waiting for scarce water rations. At the heart of this story is Isabel, a 17-year-old who works as a "tee-girl" on the exclusive, well-watered golf course of the country club. Together with her fellow tee-girls, who are easily identified by their pastel-blue uniforms, she is responsible for placing golf balls on the tee for affluent golfers who prefer not to bend down. Alongside them are the pink-uniformed caddies, who diligently retrieve stray balls, even from the course's retention pond. While the golfers enjoy a comfortable, air-conditioned environment, the tee-girls endure cramped sleeping conditions with limited food rations amidst the sweltering heat.
As a newcomer to the job, Isabel is assigned to work for the club's president, Dr. Palanca. Upon discovering they have shared Ilocano roots, he engages her in their native language and offers to assist her if needed, igniting an unfathomable fascination in Isabel towards him. Concurrently, Clara, who has recently returned from her studies in New York, is brought to the club by her uncle, who aspires for her to join his golf equipment business and help prevent the so-called "brain drain." Observing the subservient nature of the caddies, Clara feels conflicted about her uncle's proposition.
An alert from Dr. Palanca's caddie, who was seen sleeping alongside him earlier, cautions Isabel about the dangers lurking in the country club and warns her that Dr. Palanca may not be as benevolent as he appears. When Isabel inadvertently comes into possession of a golf club left behind by Palanca, she sets out to return it. In her exploration of the country club, she encounters the president's dismissive wife, a nanny searching for a missing girl (distinguished by a dragonfly hairpin), and a fellow tee-girl who scolds her for touching leftover food from the guests. While sneaking into a bathing area, Isabel overhears a conversation between Palanca and Clara's uncle. Their exchange, delivered in a patronizing tone, revolves around his family's land in Ilocos, which is jeopardized by the agrarian reform program initiated in 1988.
Isabel eventually discovers a sleeping Dr. Palanca in his office. Through the window, she witnesses workers cutting down a pine tree and loading it on a truck emblazoned with Palanca's image—the same kind of truck that once violently displaced her family from their land for development purposes. With the realization that Palanca's family was involved in her family's eviction, Isabel raises the golf club as if to strike him but hesitates. Meanwhile, Clara retreats into a thicket to fetch a misfired golf ball, avoiding the need to direct her caddie. In her search, she discovers the dragonfly hairpin, the lifeless body of the missing girl, and a bloodied golf ball that is suggested to be the one she originally sought. Clara's uncle coldly instructs a caddie to assist him in disposing of the child's corpse in the retention pond while an emotionally overwhelmed Clara is driven away.
As Isabel navigates the club's grounds, she reaches the retention pond and makes the grim discovery of the discarded body. Her desperate cries for help echo in the silence, going unanswered. As the film progresses toward its closing moments, she wades into the water, seemingly attempting to recover the child, even as golfers continue their games nonchalantly in the foreground, and the truck carrying the felled pine tree rolls past. The screen fades to black before she reemerges from the water, leaving the audience in a haunting silence.
