The story is lengthy and complicated - I think this worked against it because there were far too many characters with small parts to keep track of.
Kang-Woo is an insurance investigator until his wife and child are killed in a plane crash. He then leaves the company and starts one of his own - Mad Dog.
He is joined in this friends, Cheetah, an ex con, Noo-ri, a genius hacker type young man and Ha-ri, a young woman who has been in love with him for a while it seems. Later they are joined by Min-joon - a somewhat arrogant young man seeking to prove that his pilot brother did not commit suicide thus bringing down the plane deliberately and killing many on board.
This part is played by Do-Hwan, and the major reason I kept watching such a convoluted story. Of course there is a major villain played by the excellent. Choi Won - Young. I have to say I prefer him as a goodie, but no goodie would wear a tie in the half in half out of the collar style as he did here - one wonders at what goes on in the heads of designers - and what doesn't go on in the heads of those that wear their efforts. But then South Korean fashions - particularly for women and bizarre beyond belief.
The series is too long at sixteen episodes and the interest is not really maintained when our five intrepid heroes are off screen.
Particularly Do Hwan - or did I mention that !!
Worth a watch - but it does sag in the middle.
