A man wakes up to find his face, his name, and his entire life stolen — that’s the terrifying hook behind Netflix’s newest K-thriller, *Mousetrap*. The streamer just dropped the main poster and teaser, and it’s already got fans buzzing over its doppelgänger mystery.

Based on a popular webtoon, the show follows reclusive novelist Moon Jae, played by Ryu Jun Yeol, who loses everything to a mysterious figure known only as “The Rat” — a man with his exact face. Desperate to reclaim his identity, Moon Jae is dragged into an uneasy alliance with No Ja (Sol Kyung Gu), a loan shark chasing his own missing money, while detective Sun Yong (Lee Kyu Hyung) investigates the case from the outside, growing more confused about who’s real and who’s fake.
