### Plot and premise
The story pairs a police investigation with a developing relationship between two women. Inspector Tul, newly transferred to the Special Investigation Unit, works with the forensic doctor Cherran on a murder whose method resembles the work of a serial killer active 18 years earlier, a killer who was recently released from prison and whose return spreads fear through the capital.[2](https://mgronline.com/drama/detail/9670000112778) The central question the series poses is whether the new killing is the work of the "Raindrop Killer" (ฆาตกรหยดฝน) or a copycat.[5](https://www.iq.com/album/petrichor-2024-ar002mup45?lang=en_us)
The premiere episode, titled "A Rainy Night, A Murder, and A Fateful Encounter" (การพบกันและการฆาตกรรมในคืนวันฝนตก), opens with the death of a billionaire's son found lifeless inside his luxury car, and sets the two leads against each other over the case before their investigation draws them together.[1](https://missgrand.com/%e0%b8%ad%e0%b8%b4%e0%b8%87%e0%b8%9f%e0%b9%89%e0%b8%b2-%e0%b8%8a%e0%b8%b2%e0%b8%a5%e0%b9%87%e0%b8%ad%e0%b8%95-%e0%b8%82%e0%b8%ad%e0%b8%9e%e0%b8%a5%e0%b8%b4%e0%b8%81%e0%b8%9a%e0%b8%97/) • [7](https://www.naewna.com/entertain/843065) Tul and Cherran have differing work styles that create tension before they learn to trust each other.[3](https://mydramalist.com/763563-petrichor)
