Makoto Toda was an earnest man who had lived an ordinary life, working as an ordinary company employee. He had built himself an average, but happy home along with his wife and his daughter. Things change however, when a new female recruit named Saya arrives at Makoto’s division. The young woman does everything she can think of to get herself closer to Makoto, and it isn’t long before the two become sexually involved. The affair first seemed as though it would end as a quiet secret only the two would ever know... However, the secret escalates slowly until it spins out of control, and Makoto’s home heads toward destruction...

Saya had planned a scheme so that Sakiko, who works under Makoto, would witness her sexual affair with Makoto in the office. Makoto’s home is about to become a broken one when his wife Sachiko is told of her husband’s unfaithful doings. Saya, simmering with bottomless vengeance, exploits Hayakawa, Makoto’s daughter’s private tutor, to lure Sachiko into committing adultery... and in the end, nothing can hold down sexual desires!
