Mari (Erina Aoyama) and Rin (Rina Yuki) have known each other since elementary school. They are both dancers who admire the legendary stripper Masae Shindo. One day, Mari receives a proposal from Takao (Salmon Salmon), an avid fan. Takao's profile as the sergeant of a high-class inn in Yamanashi is enough to make her fall in love with him. Meanwhile, Rin is dating a host, Yoshio (Ishikawa Yuya), but when he asks for money, she gets into an argument with him and breaks his nose. When Takao returns to his parents' house, his mother Mayumi (Mayuko Sasaki) is disgusted by her son's behavior and locks him in a storehouse. Mari receives the news from Takao that he has been caught by the bad guys, and decides to go to Yamanashi. Fearing that Yoshio will retaliate against her, Lin also decides to accompany Mari.
