Overview: Our World has spent the last year with journalists and protestors as they live through the most turbulent period in Hong Kong's recent history. When the British government transferred sovereignty back to China 25 years ago, it promised to protect freedom of speech, but new laws have effectively silenced all criticism. Street protests have all but stopped, pro-democracy lawmakers have been replaced by Beijing loyalists and Hong Kong's new Chief Executive is its former Security Chief, who led the crackdown. Reporter Danny Vincent has been following those who have lived through the street protest movement, both as activists and reporters, many of whom are now in prison.
