White sand, turquoise blue water. For decades, a chemical plant has been discharging its wastewater into the sea, transforming the nearby landscape into a white paradise. A voice collects memories along the beach and records them on postcards. As the shadow of the factory grows longer and traces no longer fade, she questions the linearity of her own horizon. Slowly, a toxic scent spreads and she realizes that her image of paradise is contaminated. A whale becomes stranded.
