Some dramas tease you with a poster. tvN’s upcoming spy-romance “100 Days of Deception” is doing something bolder — sending its cast on an actual undercover mission, on camera, inside the set itself.

Ahead of its October premiere, tvN has scheduled a special preview broadcast titled “100 Days of Deception: Secret Documents.” In the newly released teaser, stars **Kim You Jung**, **Park Jinyoung** (of GOT7), **Kim Hyun Joo**, **Lee Moo Saeng**, and **Jin Sun Kyu** are given a mission: find a secret document hidden inside the recreated **Japanese Government-General of Korea** building on set. Along the way, they introduce their characters and give fans a first real look at the drama’s world.

Directed by Yoo In Shik — the mind behind *Extraordinary Attorney Woo* and the *Dr. Romantic* series — the show is set during the [Japanese occupation of Korea](https://en.wikipedia.org/wiki/Korea_under_Japanese_rule), following Lee Ga Kyeong (Kim You Jung), Gyeongseong’s top pickpocket turned undercover independence-movement spy, as she infiltrates enemy territory and gets entangled with interpreter Kim Tae Woong (Park Jinyoung) — who’s secretly hiding an identity of his own.
