The president of a video game company is murdered in his home, and the managing director, Nishioka (Kyusaku Shimada), is arrested. Hideki (Masanobu Takashima), the president's son, asks the Ikarime Law Office to defend Nishioka. Fukayama (Matsumoto Jun) and his team interview Nishioka, who denies the charges, and inspect the crime scene. In order to prove his innocence, they needed to overturn evidence that Nishioka's fingerprints were left on the murder weapon, a vase.
