Diving Deep into Memories of the Past

During the War of Resistance Against Japan, the Japanese army sought to seize Changsha without a hitch. To that end, they activated “Black Butler,” a strategic agent who had been embedded in China for fifteen years, and set in motion a long-planned deception campaign. Yun Muzhi, a member of the Chinese Communist Party's underground, was killed while investigating Black Butler. Unaware of his father's true identity, Yun Hongshen returned to his hometown of Changsha to track down his father's killer, only to fall straight into the trap Black Butler had laid long ago. Just as he was lost and helpless, Yang Ziming, his father's old friend and a fellow underground party member, came to his aid and protected him.
