Bad taste is the name of the game in this gory, gothic parody from South Korea.

The uniformed schoolgirl hooker of the title is plying her trade against a wall in a Seoul back street when she is discovered by her teacher, a sinister, scary man with bad skin, a demonic stare and a maniacal cackle. He offers to overlook her transgression so long as he can have a "50 grand special".

She agrees happily, saying she has always loved him ("I always gave you freebies, teacher").

Unfortunately, when they go back to his for sex, he and his three strange brothers kill her, cut her up and then reconstruct her as killer cyborg. This is not the end though: like Frankenstein's monster, the creation soon turns on its creator.

It sounds more fun than it is. As well as a goodly supply of ketchup, guns and gore, director Nam Gee-Woony uses every effect in the B movie handbook (wide angle shots, severe colour toning, harsh lighting, changes in film speed, etc), and invents a few of his own to create the weirdest atmosphere. Occasionally, it is funny. However, scenes are drawn out too long (teacher's cackling never seems to end) and with little beef to the story it's a tedious wait for the final showdown.
