A newbie detective/profiler, Park Hae Young (Lee Je Hoon), finds a walkie talkie that is broadcasting through time from Hae Young's time of 2015 from 2000. Hae Young has been assigned to a cold case unit who is tasked with solving crimes where the trail of evidence has gone cold. It is more of a political move than any real attempt to solve the crimes in terms of the "higher ups." On the other end of the line is Lee Jae Han (Jo Jin Woong) who is able to get clues from Hae Young about crimes that "occurred" and change or prevent the events. Cha Soo Hyun (Kim Hye Soo) is a female dectective who leads the cold case team. She knows Jae Han well as she was once a rookie on his team. I liked this but what slightly ruined it for me was it ended very nebulously. Some like it when it "leaves you to wonder" - I am not one of them. I understand there MAY be a second season but without that being a certainty the ending just didn't do it for me. I liked all the characters, the suspense and cases, but the ending is what really determined how I felt about this overall. Many really liked this - it rates very high. A lot of folks rate this higher than Tunnel. I preferred Tunnel. That had similar intrigue and was based on some of the same real murder cases. However, that story for me was more logically flowing and the ending felt complete. Worth the watch but be aware the ending is not neatly tied up.

The reviewers giving 9/10 ratings to this are suspicious to me. This police procedural has many plot holes and loose ends and implausible events. Mostly has rude characters yelling at each other and hitting each other and going into hysterics over small things. The character Cha is pretty but has zero personality. Might as well be a mannequin. No one seems to ever search for the body of the girl kidnapped in ep1 .

Unbearable and frustrating to watch the last few episodes to say the least. A very good plot let down by the need to make it extra dramatic and soapy. What a letdown!

Yikes. The one plot device everyone raves about is the one thing that bored me silly with this: Present day detectives are communicating through time & space with a counterpart from their past. Oh Lord. I'm sure there's all sorts of metaphors & mysticism I'm missing here, but the bottom line is it just wasn't believable to me and I quickly lost interest. I dunno, if you enjoy the Marvel/DC world where characters have some kind of superhuman power that you & me will never have, then this contemporary Korean police series may be right up your alley. I was trying to compare this our with Law & Order SVU, but it's apples & oranges - Benson & her squad figure stuff out, in Signal Cha and her staff wait for the supernatural to tell the what to do.

If you like movies and series that talk about time travel and full of mystery this series is totally for you to watch.The writer of this series made a phenomenal job with some mind twist ideas every episode hook you up till the last minute all 16 episodes are full of excitement and you don't get bored at all 10/10 would recommend it and i hope to see season 2 for it.
