My Boss is a Serial Killer

Starting from the Title-Trailer and Movie, they are not connected to each other. Confusing storyline and unexpected film ending. About a psychopath who works in a well-known company. Who is the real killer between Boss & Manager? At the end of the film a lot of violence against women. Maybe you are uncomfortable with a spectacle like this. Women who are useless at work will be killed. I was interested in watching this film because of Ice Preechya. However, this film has its funny, tense and psychological aspects. It doesn't hurt to watch, right? Fans from Indonesia.
