During fourth period, high schooler Da-jeong finds his classmate Tae-gyu dead in a classroom and Jeong-hun standing in front of him with blood on his clothes. In order to stop Jeong-hun from becoming the prime suspect, Da-jeong must help him find the real murderer, who is still inside the school building, under 40 minutes before period four ends.
I actually liked it. It kind of reminded me of Detective Conan episodes I’ve watched a few times.You just kept looking at the time with them until 4th period is over. Pulse racing and all… as slowly truths and clues are told.
Knowing how weird Korean stories are, this movie is kind of brutal but I think their target audience of course are the younger ones, mostly teenyboppers. It kind of made me worry that they might happen in school at any given day. The younger generation imitate everything they see on TV nowadays. I hope not this one. Also, this movie showcases the twisted mind of a teacher. So please, let’s be patient with our teachers too… the same way they are patient with us. A good I’m-your-student-and-you-are-my-teacher relationship isn’t bad at all.
I’ve seen the even more brutal Battle Royale, and 4th Period Mystery is a whole lot milder than the former but still kind of dangerous, in my opinion. Although the story is 50 percent focused on a love story, there are still scenes not suitable for the young audience.A murder is still a murder story no matter how they try to mask it.
