Lin Mei-ling, 37 years old, is a singer by profession. Her beauty makes her immensely popular among foreigners, but her true identity is that of an elite member of the honey trap specialist unit of the intelligence agency of Country C. She is in Japan this time with her former boss, who previously succeeded in infiltrating the country as a Japanese, to obtain the highest level of national defense information... but she was once subjected to horrific sexual training by her boss day and night, and secretly harbors an intense, perverse love that goes beyond hierarchical relationships. From disguise to bribery to betrayal, the world of intelligence is a game of life and death where every means is used.
