This is the most stupid series I've ever seen. Two not very wise undercover agents try to discover who kidnapped a girl and murdered man. When some of the characters beat a man, one of the undercover agents do nothing to stop them. When another character tries to obtain a diary which is the most important piece of evidence the policewoman let her. So this character destroys the evidence. These are the dumbest policemen on earth. Don't waste your time watching this. It is worthless.
