The film consists of three parts with Mako playing the main character in each part, featuring the lustful country girls on a sweltering summer day. The first part is about a childhood friend who has just returned from Tokyo. The second part focuses on someone who was born and raised in this area alongside Mako. The third part introduces a handsome and stylish senpai, whom Mako secretly loves, also just returning from the city. But none can resist Mako's beauty in her sheer, revealing outfit, her skin glistening with sweat. The two dive into each other, licking each drop of sweat off each other's bodies, enjoying sexual pleasures together to forget this sweltering summer heat.
