Childhood friends Miku and Kota are aware of their feelings for each other, but they have never even kissed. They go on a trekking trip, confess their feelings on the way, and start dating. However, perhaps because they were too excited, they get lost... and end up at a guesthouse. There, they find a brood of devilish men who gang rape women under the pretense of caring for them. One after another, the vulgar men come to the guesthouse and gang rape them... Miku loses her mind, and soon she is pregnant with a child, not knowing who it is...
