As the novel coronavirus begins to spread across China, two undercover journalists from Beijing travel to Wuhan to investigate the origins of the outbreak and the reality of the situation on the ground. Their journey takes them through the city's hospitals and the now-sealed Huanan Seafood Market, where they encounter a populace increasingly gripped by fear and uncertainty. Despite facing constant surveillance and obstruction from local authorities, the journalists persist in their efforts to uncover the truth, documenting the human cost of the crisis and the challenges faced by those caught in the middle of a rapidly escalating public health emergency.
