This story is about Glico Morinaga Jiken, which is one of the biggest cold cases happened in 1980s.

This unsolved case has a lot of mysteries.
・The first incident was kidnapping. A president of a large food company was kidnapped all of a sudden and culprits demanded a huge ransom, but he managed to escape three days later.
・After this incident, many food companies received blackmail, demeaning huge money and threatening food poisoning, fortunately no one became sick or dead though.
・Culprits used at least 3 children’s voice for threatening, one of them were estimated 10 years old or so.
・One member of the guilty party was seen by police twice, nevertheless, police failed to catch him.
・At last culprits didn’t get a penny.
This movie gave one hypothesis about who the culprits were and what they would have wanted was, based on these mysteries.

Some scenes were a bit cheesy or easily predictable. Most of all actors in this movie speak Kansai dialect, but some of them had weird accent. ———But story itself was really interesting and I like this.
