That’s the terrifying premise behind Netflix’s upcoming thriller **“Mousetrap,”** and the newly released stills starring **Ryu Jun Yeol** are already stirring up unease online — in the best way possible.

### A Modern Nightmare Rooted in Folklore

Based on a webtoon, “Mousetrap” follows Moon Jae (Ryu Jun Yeol), a reclusive novelist who wakes up one day to find his name, identity, and fortune stolen by a mysterious figure known only as “The Rat.” Caught in the chaos are Noja (Sul Kyung Gu), a loan shark chasing his lost money, and detective Sun Yong (Lee Kyu Hyung), pulled into the case as he hunts for The Rat’s true identity.

The eerie inspiration comes from the classic Korean folktale, [The Field Mouse That Ate a Fingernail](https://en.wikipedia.org/wiki/The_Field_Mouse_That_Ate_a_Fingernail), where a mouse devours a person’s nail clipping, transforms into their exact double, and quietly takes over their life. One chilling still even shows Moon Jae clipping his nails — a small detail with massive implications.
