Netflix is scheduled to release the thriller series Mousetrap in the third quarter of 2026, with industry reports pointing toward an August 28 premiere. Based on the Kakao Webtoon Field Mouse by Ludvico, the series features actors Ryu Jun-yeol and Sul Kyung-gu in a narrative centered on identity theft and high-stakes pursuit.
Plot and Source Material
Mousetrap follows the story of a reclusive writer, Je Mun-jae, whose life is dismantled after he discovers his identity, financial assets, and professional history have been usurped by a mysterious figure known only as "Rat." The narrative depicts Mun-jae’s descent from isolation into a desperate struggle to reclaim his existence, forcing him to collaborate with a ruthless loan shark and a private investigator.
The series is adapted from the webtoon Field Mouse, which ran from 2017 to 2020. The adaptation is categorized as TV-MA, focusing on themes of digital security, conspiracy, and personal identity. Unlike traditional K-drama formats that prioritize romance, the production is designed as a character-driven thriller.
Cast and Production Roles
The series features a pairing between Ryu Jun-yeol and Sul Kyung-gu, whose professional history and age dynamic have become a focal point of pre-release interest.
- Ryu Jun-yeol as Je Mun-jae: A novelist struggling with social phobia who must confront the public to prove his identity. Ryu is known for his previous roles in The 8 Show, Reply 1988, and A Taxi Driver.
- Sul Kyung-gu as No Ja: A loan shark who crosses paths with Mun-jae while tracking debtors. Sul’s credits include The Whirlwind, The Merciless, and Kill Boksoon.
The production team is led by director Kim Hong-seon, a veteran of the thriller genre. The screenplay is written by Lee Jae-gon, with a musical score composed by Kim Tae-seong. The series is a production of H House, C-JeS Studios, and Kakao Entertainment.
Release and Distribution Status
Mousetrap is a Netflix original series and will be available exclusively through the platform. While Netflix has not issued a finalized calendar date, current internal scheduling targets the July-to-September 2026 window.
Principal photography for the series concluded in November 2025, following a production period that began in mid-April of that year. The project is currently in post-production, where the focus remains on visual editing and final sound design.
As of now, no official full-length trailer has been released to the public. Netflix has released a ten-second promotional clip via social media channels featuring a brief action sequence, but official marketing materials remain limited as the platform prepares for the 2026 launch.
