Shen Mubai is the young master of the mortuary in the French Concession. He collects corpses at night and sells antiques at dawn. No one knows his other side - the special intelligence agent of the Chinese Communist Party, codenamed "Gramophone".
He can make the dead speak.
By touching the body of a martyr, he knew who the traitor was; by touching a blood-stained pen, he knew where the codebook was hidden; by touching a rag thrown from No. 76, He knew who was to be arrested next.
