SYNOPSIS: Jae-in has to relive the terror of her high school life to find Young-jae, a prime witness against Mob boss Du-sang. As she tries to befriend an anti-socialite Seung-hee, daughter of Young-jae, she continuously struggles in adapting a new life style. Her being an undercover student wasn't as easy as she thought it would be. She has to deal, not only with the school demands, but also to students who acts like thugs. Despite all the troubles, she found happiness in Seung-hee's friendship and No-young's love. But as everything seems to be running as planned, she found out that somebody in their team is a spy for Du-sang.

REVIEWS: I thought of "Never Been Kissed" when Jae-in became an undercover student to get first hand information and fell in love with a student. It looks like the idea would be similar but luckily, it became much more interesting than the movie.

Finally, I get to see the other side of Kim Sam-soon. Everything she does in the movie makes me laugh. When she talks, my memory of Sam-soon flashes back because of her distinct tone. She sounded like a cartoon character. Actually, its one of her assets. To have a comical voice makes every dialogue funnier. And when she does her action routines like the splits and the flying kicks, it looks hilarious.

May it be action or romance, Seon-ah knows how to tickle your funny bones. It only proves that she is one hell of a natural comedienne. She doesn't have to act because her comedy comes out at its best.
