The Last Witness (2015)

Sadato Sakata was a highly regarded public prosecutor but now has his own law practice and specializes in criminal cases. One day, Sadato accepts a request to defend a successful businessman accused of murdering a woman he was having an affair with. The crime appears open and shut: fingerprints, bloodstains, and security camera footage all indicate Kuniaki Shimazu is guilty. But Shimazu insists he is innocent, and Sadato’s intuition leads him to accept the case.
