Hero (2007)

After six years away, D.A. Kuryu Kohei (Kimura Takuya) returns to his former Josai branch of the Tokyo District Public Prosecutors Office, just in time for a brewing storm. Kohei's first case starts out simple enough. The suspect, a blonde-haired security guard, had already confessed to manslaughter, but he suddenly retracts his confession and takes things to court with big-shot defense attorney Gamo (Matsumoto Koshiro). It turns out that the security guard is a key alibi witness in a high-profile political corruption case, and the results of his case will directly affect the next. With the media, politicians, and a special investigative team breathing down his back, Kohei must handle the case with care (and flair) to find out the truth.
