Someone Stole His Identity — Now “Mousetrap” Wants It Back

Imagine waking up to find your fingerprint no longer unlocks your own phone, and the one friend who managed your life has vanished without a trace. That’s the nightmare fueling Mousetrap, Netflix’s upcoming K-drama thriller eyeing an August 2026 release, led by veteran actors Sul Kyung Gu and Ryu Jun Yeol.

Mousetrap: Key Details

The Premise: Stolen Identity, Real Stakes

The story follows Moon Jae, a reclusive novelist whose entire identity is quietly hijacked by a mysterious figure known only as “Rat” — his fingerprint access fails, his trusted contact disappears, and he’s left unable to even prove he is who he says he is. Determined to reclaim his life, Moon Jae sets out to track down the impostor who’s taken over his name, his fortune, and his future.

Who’s Behind the Characters

Ryu Jun Yeol, known for The 8 Show, Reply 1988, and the film Alienoid, plays Moon Jae — a socially withdrawn writer suddenly forced out of isolation by circumstance. Sul Kyung Gu, seen previously in The Whirlwind and Kill Bok Soon, plays No Ja, a loan shark and private detective who’s been hunting Moon Jae for unpaid debts. When Moon Jae resurfaces three years later, No Ja gets pulled into the identity-theft mystery himself, motivated purely by the money he’s owed.

When Can You Actually Watch It?

Netflix has confirmed Mousetrap for its 2026 Korean slate, placing it in the Q3 window. A specific date — August 28 — has surfaced from a K-drama tracking source, though Netflix itself hasn’t made it official yet. As always with unconfirmed drops, treat the date as a strong possibility rather than a lock.

Identity theft as a thriller premise taps into a very real, well-documented modern anxiety — you can read more about the phenomenon on Wikipedia’s identity theft entry.
