Cha Geon U loses his beloved in a police mission. Unable to get over the loss, he decides to join a police unit lead by Jang Mu Won, the brother of the deceased woman. Soon, he and his team walk into a risky game with dangerous criminals where he discovers the true colours of his profession.
Hidden Identity shows how a great crime drama can be entertaining, thrilling and heart felt all at the same time.
The story, at its' core is pretty basic; there's a big bad that the team is trying to catch, and most of the team members have personal issues with said big bad. What separates this show are the embellishments and details. There's a steady buildup to revealing the big bad, so that you're eager. There's red herrings and actual clues, so you can figure it out along with. And not once does the show pull punches; the stakes are as big as they're made out to be.
The acting is great, with good camaraderie and the villains are evil but with hints of humanity when needed.
The largest downside is the slight dragging of the show in the middle. Not enough to be boring, but in a show with so many other strengths, a glaring flaw.
