Chen Tao, a Chinese undertaker at the Japanese Expatriate Funeral Home in Tianjin, used his position to intercept information from the remains of Japanese soldiers. When a body recording top-secret bacterial warfare information code-named "Desolation" was delivered to the eyes, the appearance of calm was completely broken.

This secret war, with corpses as the battlefield and ashes as cover, became the last line of defense for millions of people in North China for the first time.
