Suzy (middle right), the rich chairman's only daughter and three guys are the newcomers of the Gangnam Police Station, where things get pretty crazy when they arrive. And the four of them are made in a group called 'Rookie 4' because they barely passed the exams as they strive in a halarious cases and mysteries to pass the senior exams, and things start to go the wrong way when the three guys fall for her.

Who will she choose? Danny (middle left), the mysterious good looking dude that is the squad leader but is a cold person, Jackson (most left), the hot looking dude that seldom work as a team or Shawn (most right), the nerdy and forgetful ugly looking dude that didn't really like his hairstyle.

NOTE: This contains a lot of unpolite words, just to let you know.
