When a woman in Oregon opens a box of Halloween decorations and finds a distressing letter written by a political prisoner from inside a Chinese labour camp, her discovery makes waves across major news outlets worldwide. Meanwhile, the author of the letter, Sun Yi, breaks through internet firewalls to learn about the attention his letter has received and joins forces with an underground network of journalists and Chinese dissidents to reveal his entire story. From Peabody Award–winning director Leon Lee, Letter From Masanjia takes us deep into the horrific realities of China's labour camps through the eyes of Sun Yi, who's determined to expose these unthinkable human rights violations. Despite being hotly pursued by local authorities, he stops at nothing to find justice, ultimately leading to large-scale reform of China's labour camp system. Mariam Zaidi
