Where can a wrongly accused person turn to for help? Kwon Soon Tae (Kim Sang Ho) was a law-abiding single father raising his daughter, Kwon Dong Hyun (Kim Hyang Gi), when his whole world turns upside after he is wrongly accused of murder and sent to prison. Soon Tae writes a letter pleading his innocence and asking for help and sends it to Choi Pil Jae (Kim Myung Min), a police detective that Soon Tae believed was righteous. But Pil Jae had already quit his job as a detective after his partner betrayed him and now works as an illegal law broker at a law firm. Pil Jae disregards Soon Tae’s letter at first, but when he realizes that it was a case handled by his former partner, Pil Jae is intrigued. Will he put his detective skills back into use to crack this murder case and help prove Soon Tae’s innocence? “Proof of Innocence” is a 2016 South Korean film written and directed by Kwon Jong Kwan.
