Let's check out the official trailer for Undercover High School!




What can we expect from the plot?


Seo plays National Intelligence Service (NIS) agent Jung Hae Sung, who we first see entering from on high as he swoops in on the illegal sale of a prized Buddha statue, and grins and postures heroically between skirmishes with foes on both sides of the trade.


A fist fight evolves into a daring car chase, during which he hops from a motorbike onto a moving car and smashes his way in through a sunroof with his helmet. Although he manages to get his man and retrieve the statue, his gutsy antics result in the priceless artefact losing an arm in a crash.

The higher-ups at the NIS want Hae Sung gone, but they reluctantly offer him a chance to redeem himself by taking on an important yet rather demeaning mission – go undercover in a high school and track down gold bars worth 800 billion won supposedly stashed there.





Naturally, Byeongmun High School is no ordinary institution. This venerated school welcomes only the elite and is run by a student council comprising the best of the best and the richest of the rich.


After being given a cover story and brushing up on contemporary teenage slang, Hae Sung is thrust back into school and immediately reminded of his own youth: he was bullied in school because he was an orphan his father, also a dashing NIS agent, having suffered an untimely death.




There is plenty of bullying going on at Byeongmun, much of it directed at Hae Sung’s desk mate Lee Dong Min (Shin Joon Hang). Hae Sung would love nothing more than to put the bullies in their place, but he is on strict orders to keep a low profile.


Not only can he not teach them a lesson, but when the bullies set their sights on him, he has to grin and bear it. But how long can that possibly last?


The next episodes will be released this weekend on MBC at 21:50 KST Friday and Saturday!
