"When you have eliminated the impossible, whatever remains, however improbable must be the truth."

Lee Taemin is a smart highschool student who helps the police solve crimes, where he should uncover the real truth and reveal the culprit with a series of clever deductions

"Courage is a word that gives you the strength to do what's right,you should not use it as a excuse to murder someone"

He hates murderers. He never approved of the wisdom of killing people for their own gain. 

 "There is only one truth."

Let's join him as he faces his daily task, that is to eliminate crime and find his missing older brother. 

The strong one doesn't win.The one that win is strong.
