Gokuraku BOX is an internet cafe in the suburbs.

At first glance, it looks as if it's not a popular place. But it has become a castle of lawlessness and lust, where a man who has done all kinds of evil with the power of his family has been assigned.

Then three unknowing women come to trap them.

The women, deprived of their freedom and hope, eventually succumb to the man's control and are trapped in a cage of horrific pleasures.
