Here´s the movie synopsis from the Cannes film festival website:
“Petition – The court of the complainants”, directed by Zhao Liang, is a unique testimony about China today. Since 1996 Zhao Liang has filmed the “petitioners”, who come from all over China to make complaints in Beijing about abuses and injustices committed by the local authorities. Gathered near the complaints offices, around the southern railway station of Beijing, living in most cases in makeshift shelters, the complainants wait for months or years to obtain justice. Peasants thrown off their land, workers from factories which have gone into liquidation, small homeowners who have seen their houses demolished but received no compensation…, all types of cases are represented. Faced with the most brutal intimidation from the local authorities, the complainants who stubbornly continue despite everything find that their hopes are often vain. Zhao Liang has accompanied several of them, particularly a mother and her daughter, whose full story we follow over ten years. A film shot right up to the start of the Olympic Games in direct contact with realities, showing the persistent contradictions of China in the midst of powerful economic expansion.
Those who cannot find the DVD can watch the movie with French subtitles on YouTube (try accessing the site through KTunnel if you are behind the GFW).
