In the quiet atmosphere of rural Japan, the hidden passions of middle-aged men and women simmer beneath the surface. Amidst sprawling blue skies and lush green landscapes, men and women seek secret romance in secluded, hidden spots far from their ordinary lives. A mother sneaking away from her husband to be with a neighbor, a sister who left home after losing affection for her spouse, a depraved father who crosses boundaries by seducing his own daughter despite being a teacher, and a lustful older woman who willingly opens her legs for a lecherous old man—each character's suppressed desires gradually ignite, fueled by the summer breeze. Across seven stories spanning 180 minutes, increasingly outrageous and erotic scenarios unfold one after another. Behind the masks of everyday life, raw human desires emerge sharply and vividly. This provocative 180-minute narrative maximizes the erotic essence of summer.
