Vietnamese twins, bound by blood and desire, sneak into each other's room under the cover of night. In the soft glow of a bedside lamp, they explore each other's bodies, learning the curves and contours, the sensitive spots that make them gasp. They're just beginning to find their rhythm when a sudden creak of the floorboard makes them freeze. Their parents stand in the doorway, eyes wide with shock and disbelief, catching the twins in the act of their taboo love.
