As a tropical storm batters the Dominican Republic, two sisters retreat to their cramped apartment, their boredom and pent-up sexual frustration growing with each passing hour. The older sister, a dominant force in her daily life, begins to direct her sibling in a provocative dance, their bodies pressed close in the humid, rain-soaked room. Their clothes cling to their curves, revealing every line and contour as the younger sister submits to her sister's dominant touch. The storm rages on outside, mirroring the intense, taboo passion that builds between them.
