Its a good movie, I heard that it comes from a true story that is why I decided to watched it plus Mi Ran iscthe lead star she's one of the good actresses in So. Korea. Deok Hee who has gone through a lot of hardship in life plus sje was victimized from a voice phising scam that took her hard earned savings. Her children werectaken away from her because she has no enough savings to sustain them. That is why she decided to solve this case to take back her money. With the help of the slayed victim of the syndicate Jae Min or what she called Mr. Son, they both worked together to capture the big boss. They managed to solved the case with the help of her friends who were just an ordinary citizen.
Very satisfying ending they managed to solved the case and brings back their normal life.
