[Crime Solving and Criminal Investigation] + [Cross-Time Communication] + [Father and Son Hunting Criminals] + [A Fresh New Premise]

While investigating a case, detective Di Zheng is on the verge of being fired when he accidentally discovers that his walkie-talkie can now connect him to his father, twenty years in the past.

Some kind of bond between father and son seems to have opened up a channel for them to speak across time.

The “Rainstorm Killer” strikes every rainy season. The criminal is extremely skilled at evading detection, and the case has gone unsolved for years?

No problem!

The 2026 case files show that his first crime took place on Shanhai Road.

Di Zheng: Could you stake out the place ahead of time, Dad? You were there twenty years ago. Help me get some clues from the scene!

A decades-old killing curse on Jinan Island?

No problem!

Di Zheng: Dad, could you look into what happened back then, twenty years ago?

A hidden ancient village, and a curse that makes corpses kill?

Di Zheng: Dad, get on it!

Thanks to their cross-time conversations, Di Zheng always has more clues than anyone else. He solves one cold case and major crime after another, steadily rising through the ranks!

And with his future son's help, his father's life takes an unexpected turn as well...
