Across three eras, eerie dreams of a red snake connect the intertwined fates of two families. In 2026, Xiao Lian’s play about her grandmother Paochu’s guerrilla tales sparks a political backlash. Seeking Paochu’s hideout with the guide, Yulao, they find a dead Vietnamese logger. In 1989, police informant JunXian breaks from his handlers after confessing to Ya-Hong, Xiao Lian’s mother, who's the editor in chief of a magazine, then is framed for robbery and is tortured by the police. In 1952, A-Kun, an idealistic enforcer for Paochu’s guerrillas is also a henchman for them. History repeats itself as love and justice struggle against a legacy of hatred.
