The Frog

The Frog unfolds in a secluded forest town, a few hours' drive from Seoul, where Jeon Yeong-ha has spent the last several years. Following his beloved wife's terminal illness, Yeong-ha moved to this tranquil location, fulfilling her dream of living in a beautiful, remote house surrounded by nature. After she died, he chose to remain in the town, residing in a modest home adjacent to the villa he now operates as a holiday rental. His daughter, Ui-seon, frequently urges him to return to Seoul to live with her and her fiancé, but Yeong-ha finds solace in managing the rental alongside his best friend, Yong-chae. However, Yeong-ha lacks the drive to fully commit to the business, relying on Yong-chae to encourage him to promote the property online to attract more guests. Amidst this backdrop, a young woman named Seong-a arrives at the rental with her son, Si-hyeon. Though she carries an air of mystery and reserve, Yeong-ha welcomes them without hesitation. His sense of unease grows when Seong-a departs early the next morning, leaving behind disturbing blood stains and an overpowering scent of bleach, most alarmingly without her son in tow. The narrative also weaves in a chilling incident from over twenty years ago at the Lake View Motel, run by Gu Sang-jun and his wife, Eun-gyeong. In the early 2000s, Sang-jun's hospitality took a dark turn when he invited a serious-looking man, later identified as the serial killer Hyang-cheol, to stay the night. Despite being off-season and desperate for business, Sang-jun offered the guest the best room at a nominal fee. This fateful decision shattered Sang-jun's life when Hyang-cheol committed a brutal murder within the motel's walls. Though the killer was apprehended swiftly, the motel's reputation suffered irreparable damage. As the specter of crime looms over both timelines, a singular thread connects them: Officer Yoon Bo-min. With an innate talent for solving crimes, Bo-min began her career at the Hosu police station just days before Hyang-cheol's horrific act. She witnessed the motel's decline and the profound impact of the murder on Sang-jun and his family. Now, as a high-ranking officer returning to the same station, she begins to observe unsettling behavior from Yeong-ha and his enigmatic guest, Seong-a, hinting at a deeper, intertwining mystery waiting to be unraveled.
