Mary lives with her son by a previous marriage after her husband dies. She has a faint romantic interest in her son, who reminds her of her late husband. They go on a trip to a hot spring together...but even though they are officially registered as father and son, they are strangers. Even though they know they are not supposed to do this... a forbidden bond binds them together. Unable to resist the pleasure of immorality, the two make love on a night in Jyoshu...they can't take it anymore. The panting of parent and child echoes incessantly in the darkness of the night.
