In 1941, in the occupied Wuhan, Fan Mingyin, an underground member of the Chinese Communist Party, lurked as a "traitor". In order to transport the top-secret radio station and the seriously injured people out of the city, the organization planned a funeral breakout with his fake death as the core. The funeral procession stretched for miles, and there was hidden life inside the double-layered coffin. When the suspicious Japanese master Shoichi Yoshida orders the coffin to be opened at the funeral, Fan Mingyin must use his life as a bet to protect the secrets in the coffin in full view of the public. A life-and-death game played out in front of the enemy's eyes quietly began at the traitor's grand funeral.
