Sun Woo’s passion cools down and he slowly loses his vision as a maritime policeman. Then one day, Jung Ryul, who has formed a new crime investigation section in Incheon city, visits Sun Woo and asks him to join the team.

    @15 Kdaddict

    This lead actress acted in Mischievous Kiss & Born to be rich as 2nd lead – she acted quite crazy & a spoilt brad in that 2 dramas which gave me not so good impression. 🙂

    I get to know Choi Si Won in Oh My lady & I like him.
    Chae Rim is one of my fav actress. 🙂

    KDaddict Says:

    @OK OK OK,
    Good to see you. I saw Mischievous Kiss. You mean the main actress in it? But the photos above look so diff. The actress didn’t leave a gd impression on me either.
    Chae Rim is one of my fav actresses too. Love her in DaJa’s Spring!

    OK OK OK Says:

    @17 Kdaddict

    Lee Si Young is 1 of main actress but not the 1st lead actress that ended up with Kim Hyun Joon.

    Lee Si Young is after Kim Hyun Joon in Mischievous Kiss but he likes the 1st lead actress Jung So Min & marry her. 😉

    I like Chae Rim ever since after she acted in All About Eve with Jang Dong Gun, later she also acted in Loving You 1999 production. She looks lovelier in early days. Taiwan or China production i didn’t watch. 🙂

    I missing in action for around 3 wks bc I reinstall my computer & takes me quite a while to reinstall everything. 🙂

    Now starting to catch up all the dramas i like

    Jennie Says:

    This drama has been given a lot of publicity, probably due to Choi Si Won. Liked him in Oh My Lady but am not a fan of the lead actress, Lee Si Young. Didn’t like her in Mischievious Kiss at all. She was quite ok in Born to be rich but something abt her just doesn’t click with me.

    KDaddict Says:

    Ep 1:
    Wow! This is seriously impressive! All the hardware (hovercraft, heli, planes, control room set up), all the men in black (SWAT team or SSAT team tough guys) wearing black visors (day), or night vision goggles (nite) make it look like one kick-ass drama! There have never been so many macho men in one KD before! It is really a sight for sore eyes. The one weak link is that leading actress. She looks fine as a nurse’s aid on the beach dispensing band-aids, but looks completely out of her depth as an investigative cop out to bring down the criminal world.
    There r so few good KDs showing rt now. So this is indeed a welcome broadcast!!

    m gonna watch this drama coz it has choi siwon in lead role nd i love him…..

    KDaddict Says:

    For all the enthusiasm that ep 1 aroused in me (#34), I failed to finish ep 2. I got stuck at where the leading actress is doing a lot of talking with her colleagues.
    Strange! It is not that she isn’t pretty. It may be that she isn’t pretty in a leading lady kind of way. I just keep walking away fr the screen when she is on, and don’t seem to continue. That’s just my strange reaction to this girl. I’m sure the show itself is a v good show. Enjoy!
