SINOPSIS
The drama is an investigative police thriller, and invents a new police department (in addition to the existing departments for criminal investigations, special investigations, criminal affairs, and white collar crime) that’ll be the focus of the show. They’ll hunt down criminals and investigate crimes while undercover (hence the title), and members will include a late-twenties male senior police officer, an early-forties male chief superintendent, and a twentysomething female senior officer.
