Kyung Jin, a police officer, on her day off is forced back on duty when she is caught chasing down a bag-snatcher. The "bag-snatcher" turns out to be Myung Woo, a passer-by who was trying to catch the actual criminal. With a twist of fate, the two are paired together after Myung Woo volunteers to be on patrol looking out for unruly students. This is the second of the "My Sassy Girl Trilogy" by Director/Screenwriter Kwak Jae-Young. The first is the 2001 film "My Sassy Girl". The third is the 2008 Japanese film "Cyborg She". They are unrelated except for having a sassy girl theme.
