In mid-January 2020, as Chinese New Year celebrations begin, two journalists travel from Beijing to Wuhan to investigate reports of a new respiratory illness spreading through the city. The film follows their attempts to get answers from hospitals, officials, and residents in the days just before the city was sealed off, capturing the confusion and fear on the ground as authorities scramble to control both the outbreak and the narrative around it. Interviews and on-the-street footage trace how a local health scare turned, within seventy-two hours, into the opening chapter of a global pandemic. The reporters' access shrinks visibly as the story progresses, official statements grow more guarded, and the streets empty out in real time. Rather than reconstructing the outbreak from hindsight, the film stays inside those three days, showing what was known, suspected, and hidden as the lockdown took shape around the journalists themselves.
