HSU Tzu-chiang was pronounced guilty and sentenced to death in a 1995 kidnap and murder case despite the lack of forensic evidence. After a 16-year effort by NGOs, HSU was released with a life sentence in 2016. Now he continues to fight to prove his innocence. Director Chi has been documenting Hsu's story since 2012. The journey brought Chi face-to-face with the shortcomings of human society and inspired his investigation into why the judicial system failed HSU.
