Mio, the wife of wealthy businessman Yoshida Isao, lives a life of luxury in a high-rise apartment in the heart of Tokyo.

However, deep within her heart, a sense of loneliness and confinement starts to brew, a feeling that money alone cannot fill.

It is then that Mio meets Raito, a young man working as host in Kabukicho, and gradually becomes addicted to their dangerous love affair.

Meanwhile, her husband is also continuing his affair with young mistress Yuno.

After Mio hires a private detective to conduct an investigation, she learns that Yuno is Raito’s lover, and she is even giving him the money that Yoshida pays her.

Her emotions transform into jealousy and hatred, and in a fit of rage, Mio attacks Yuno, landing her in prison for attempted murder.

Three years later, having lost everything, Mio is released, only to find herself in a world of poverty and decadence.

As Mio moves in with Hikaru, a fellow former inmate, and the troubled man living with her, she is once again drawn into a vortex of desire and violence.
