The Inquiry 1938

A high-ranking general of the Communist party goes missing and an investigation is launched to uncover the truth behind his disappearance. It was a sensitive time in the history of China as the Kuomintang and the Communists have formed an alliance. In the year 1938, Chiang Kai Shek heeds the ill-intended advice and orders the secret assassination of Xuan Xia Fu. His actions have elicited strong objections from both sides and due to rising tensions, the Kuomintang was forced to set up a designated team to investigate Xuan Xia Fu's missing case. As a former agent of the Kuomintang and a member of the Communist underground, Wu Zhong Ming is acknowledged by both parties to facilitate his investigation, thus starting him on a difficult journey for the truth.
