One of the best crime k-dramas you’ll ever come across is Signal—where an old-case profiler in 2015 and a detective in 1989 work together to solve a series of related murders spanning three decades.

The catch? They are only able to communicate through a special walkie talkie.

Using the power of both foresight and hindsight, both of them start to solve crimes by preventing them from ever taking place and soon begin to change reality (for better or worse, we’ll leave it up to you to decide).
