An unidentified middle-aged man (Toshiyuki Nishida) is found dead in his car near a camping ground on a mountain in Hokkaido. His dead dog, an Akita, lays next to him. The dog apparently died approximately six months after the man's death. There isn't any identification found on the deceased man. City Hall employee Kyousuke Okutsu (Tetsuji Tamayama) is then assigned to uncover the man's identity for a proper funeral. Kyosuke's investigation begins in earnest as he traces the man's last journey. Along the way, Kyosuke is reminded of his own past and his star watching dog Kuro.
