Mousetrap: Identity Theft Thriller Starring Sul Kyung Gu Lands on Netflix Q3 2026

Imagine waking up one day to discover someone has stolen your entire identity—your name, your money, even your fingerprints no longer recognize you. This chilling premise drives Netflix’s upcoming thriller Mousetrap, starring powerhouse actors Sul Kyung Gu and Ryu Jun Yeol. Based on the popular webtoon Field Mouse, this gripping series promises an edge-of-your-seat journey into identity theft gone terrifyingly wrong.

Mousetrap at a Glance

A Terrifying Tale of Stolen Identity

The story follows Je Mun Jae, a reclusive novelist living with social phobia whose quiet, predictable life shatters when his phone’s fingerprint recognition fails. Soon, he discovers someone called “Rat” has completely assumed his identity, stealing his fortune and erasing his existence. With no way to prove who he really is, Mun Jae must track down this mysterious imposter and reclaim his life before it’s gone forever.

Acclaimed Cast Brings Intensity to Screen

Sul Kyung Gu delivers what promises to be another compelling performance as No Ja, a ruthless loan shark who runs a private detective agency. Fans know him from Netflix hits like The Whirlwind and Kill Bok Soon. His character gets entangled in the case while trying to recover money Mun Jae owes him.

Ryu Jun Yeol portrays the tormented protagonist Je Mun Jae. Fresh off his role in The 8 Show, Ryu brings depth to this isolated writer thrust into a nightmare scenario. His previous work in Reply 1988 and the film A Taxi Driver showcases his range as an actor.

From Webtoon to Screen

Director Kim Hong Seon adapts Ludvico’s gripping webtoon Field Mouse for the small screen. The source material’s popularity among Korean readers suggests a built-in audience eager to see this psychological thriller come to life. The production wrapped filming in November 2025, with post-production now underway to meet the summer 2026 release target.

Why This Thriller Stands Out

In an era where digital identity theft feels increasingly plausible, Mousetrap taps into modern anxieties about losing control of our online and offline selves. The cat-and-mouse game between Mun Jae and the elusive “Rat” promises psychological depth alongside thriller elements, making it one of Netflix’s most anticipated 2026 releases.
