To millions of TV viewers, the name Kate Adie remains synonymous with war reporting. It became a joke in the British Army that when Adie arrived on the scene they knew they were in trouble. But there is one assignment that stands out as the most difficult of her career: reporting the massacre of hundreds of civilians in Beijing on 3 and 4 June 1989. Kate was one of the few Western television reporters out on the streets at the time and she witnessed the killings at close quarters. Twenty years on, Kate returns to China. Denied an official journalists' visa, she and her crew have to travel incognito, posing as tourists and meeting contributors in secret. she meets eyewitnesses and victims' families, who share their experiences of being labelled dissidents by China's authorities, a status that leaves them subject to police harassment and Communist Party persecution. The journey takes us to Hong Kong, Taiwan, Shanghai, Beijing and Chengdu. Despite Kate being followed and blocked from meeting some people, the film presents a compelling picture of the confrontation and the reasons behind it - "when an army was ordered to open fire on its own people".
