More than 65 million people around the world have been forced from their homes to escape famine, climate change and war. Famous Chinese artist-actyvist and filmmaker Ai Weiwei examines the staggering scale of the refugee crisis and its profoundly personal human impact. Over the course of one year in 23 countries, Weiwei follows a chain of urgent human stories that stretch across the globe, documenting the conditions in refugee camps where millions are suffering and enduring after escaping the ethnic and religious violence and economic catastrophe of their homelands. Weiwei patiently, lucidly depicts a slow-motion holocaust occurring on a planetary scale, while keeping his eyes open to the heroism of aid workers from many countries.
