When Joanna is sent away on business to Japan, she anticipates nothing unusual. However, the timing couldn't be worse: she senses that someone at work is scheming behind her back and she cannot afford to be away from her office for fear of being upstaged. On a personal level, she's just beginning to get somewhere with Harry, a young and attractive solicitor she's been pursuing for some time.
As soon as she arrives in Tokyo, her sensuality is put to the test. Enigmatic messages followed by singular encounters with strangers who seem to know her every desire. She is constantly aroused, but never entirely sated. As she gradually gives in to the magic of Japan - its people and its ways - she learns that she is becoming involved in a case of mistaken identity, erotic intrigue and mysterious seduction.
