Black-and-White Dream Shadows

The chairman of Tokyo Shinozuka Pharmaceutical Group is murdered while traveling with his wife. During the police investigation, they make an unexpected discovery: the person who jumped to his death two years earlier, supposedly taking his own life out of guilt, was not the real culprit. Someone had taken the culprit's place and brought the case to a close. As the investigation deepens, the police uncover a massive conspiracy behind the case, and the culprit from two years ago turns out to be someone else.
