Goda is a thirty-something documentary filmmaker. While his work may seem intriguing to some his life is absolutely average – long hours at the office, drinks after work, an equally busy girlfriend, Kiriko, that he's been with for a decade. One night, he returns home to find police cars and ambulances surrounding the entrance to his apartment building. When he gets upstairs he's told that Kiriko has committed with a bullet to the head. With Japan having some of the strictest set of gun control laws on the books not only is Goda left with the yawning, black "why" behind Kiriko's suicide, but also a whole other set of mysterious "hows," "wheres" and "whos." How did Kiriko get a handgun in the first place? From where? And most importantly from who?
