Woo-jin, who is a repeater of college entrance exam, and Taek-sik's friend, Kang-hee come and visit Woo-jin's hometown on a small island. Woo-jin's mom, Hyeon-sook used to work as an erotic movie actress for a short time when she was too young to make a right decision for herself. Hyeon-sook operates a small sashimi restaurant and a bed and breakfast to make a living on the island. She lives her life like a hermit, refusing to visit the land even once. Although Hyeon-sook has sex with Bong-seong, she rejects his proposals.
Although Woo-jin and Kang-hee are lovers, Kang-hee allows kisses only, but nothing else of her body, which is against Woo-jin's wishful thinking.
Woo-jin had his first sexual encounter with Hye-ri one day who stayed at the bed and breakfast; however, it happened only in his dreams.
One day, Woo-jin is terribly shocked to accidentally see his mom Hyeon-sook and Bong-seong having sex. With Woo-jin in anger, he went to Kang-hee and tried to rape her. As a result, he breaks up with Kang-hee. Hyeon-sook announces breakup to Bong-seong for her son.
Tae-sik is about to watch a DVD with erotic movies he borrowed from one of his friends. The main actress of the DVD exactly looks like Woo-jin's mom and Tae-sik starts imagining something different.
