If The Scarecrow is on your watchlist, you are probably already in the mood for something cold, unsettling, and rooted in real-life fear.
The new ENA thriller has been getting attention for its serial-murder premise and its tense investigation setup, with Park Hae-soo and Lee Hee-joon leading the story as men forced to confront a case that feels deeply personal and disturbingly familiar.
The show premiered on April 20, 2026, airs on ENA and Genie TV, and follows a retired criminal profiler who must work with a prosecutor to investigate a serial killer cold case.
What makes The Scarecrow especially gripping is its connection to Korea’s real crime history. Korean crime stories that draw from serial murder cases have long left a mark on viewers, and this drama is already being discussed in that same haunting tradition.
That is exactly why fans are searching for films and dramas with a similar mood, especially titles tied to the 1980s and 1990s, cold cases, and psychologically heavy investigations. If you want to ease into that atmosphere first, these five cult thrillers are the perfect place to start.
1. Memories of Murder (2003)
Memories of Murder remains the benchmark for Korean real-crime thrillers. Set in a rural province in 1986, the film follows detective Park Doo-man (Song Kang-ho) and detective Seo Tae-yoon (Kim Sang-kyung) as they struggle to solve a brutal series of murders.
The case grows more frustrating with every step, and that helplessness becomes the film’s most powerful emotion.
It is haunting, patient, and deeply human.

2. Signal (2016)
Signal takes the idea of cold cases and adds a unique twist.
Detective Lee Jae-han (Cho Jin-woong) from 1989 communicates with profiler Park Hae-young (Lee Je-hoon) from the present through a mysterious walkie-talkie.
Detective Cha Soo-hyun (Kim Hye-soo) becomes the emotional bridge between both timelines.

Tunnel blends crime investigation with a gripping time-shift narrative.
The story follows detective Park Gwang-ho (Choi Jin-hyuk), who is chasing a serial killer in 1986 when he suddenly travels to the present day through a mysterious tunnel.
There, he teams up with elite detective Kim Sun-jae (Yoon Hyun-min) and criminal psychologist Shin Jae-yi (Lee Yoo-young) to continue solving the same case decades later.
The drama draws clear inspiration from real-life serial murder cases, including the Hwaseong murders, which gives it a grounded yet emotionally intense tone.

Together, they study the minds of serial killers during a time when criminal profiling was still new in South Korea.
The drama is based on real cases, which makes it feel even more grounded and unsettling.
