“In this particular episode, the male protagonist, a bandit leader turned anti-Japanese hero, is detained by the Japanese occupation authorities. His wife, played by actress Ge Tian, Mr. Liu’s wife, visits him in the cell. She miraculously manages to hide an elongated stick-type grenade in her vagina and passes the guards. While being watched by the Japanese military interrogator and his Chinese collaborator, the two then perform a last act of erotic intimacy while the husband insults the Japanese emperor. When the Japanese interrogator is about to shoot the man for the royal insult, the husband pulls the grenade from his wife’s body, and the woman gleefully pulls the ignition pin, thus sacrificing their lives for the party and the motherland.”
