this IMAGE

What if a mysterious walkie-talkie from the past could allow a detective from the 1980s to talk with a detective in the present time with the common goal of solving decades-old cold cases? You can betcha it’s going to be a mind-bending binge of an experience.

“Signal” delivers this and so much more, weaving a tapestry of suspense, mystery, and a hefty dose of heart-thumping moments. If you’re not already tuning in, you’re missing out on a show that’s part detective drama, part time machine, and all kinds of addictive brain twisters.

So, what’s the scoop on “Signal”?

Get your brain to envision this. Park Hae-Young, a sharp cold case profiler, bumps into a walkie-talkie that lets him chat with a detective from the 1980s, Lee Jae-Han. Together, they crack unsolved mysteries that have been on the books for decades.

It’s like “Back to the Future” had a baby with “CSI” — only way more heart and twists to keep you guessing.

Let’s break down the squad.

We’ve got Lee Je-Hoon as Park Hae-Young, our present-day Sherlock. He’s smart, he’s driven, and yeah, he’s got some personal baggage that keeps things interesting.

Then there’s Lee Jae-Han, played by Cho Jin-Woong, our rule-bending, heart-of-gold detective from the past.

And don’t forget Kim Hye-Soo, who brings it as Cha Soo-Hyun, the kick-butt detective who connects the dots across time. This trio is nothing short of electric.

The big deal with “Signal” is its take on justice and how the past never really lets go of the present.
