In what seems to be an island paradise, two well-endowed girls called Rui and Kirei are on vacation. As time progresses, they notice that there is something unusual with the natives and the beautiful butterflies that inhabit the island. As they begin to notice these oddities, they begin to have sex with each other and the natives. The episode ends with the girls being gang raped, thrown down an oubliette, and emerging as butterflies.
