在这部徐自强的练习题纪录片片中,徐自强是一位被关了十六年的冤狱当事人，也曾经是一位面临枪决的死刑犯；纪岳君则是一位不懂法律的纪录片导演。徐自强辛苦做着生死交关的人生练习题，纪录片创作者与观众在追寻真相的过程中，其实也做着另一种考验人性的练习题，我们将会看见人类有限的能力，如何在不足的司法制度和骄傲的执法者手中，构建着那不堪一击的公平正义。这是一段让我们共同学习如何面对人生、信念、关爱与真实的旅程。
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.
