Helmed by first time feature director Chang Jeol-soo, Bedevilled is one part twisted drama, one part slasher flick. According to the official synopsis, "Hae-won is a beautiful single woman in her thirties who works at a bank in the Seoul city. She leads a busy life until she becomes a witness to an attempted murder case, and at the same time, things get complicated at work. When things get out of hand she is forced to take a vacation so she heads for 'Moodo', a small undeveloped island, where she had once visited to see her grandparents. And where she had befriended a girl named Bok-nam who stills writes to Hae-won asking her to visit despite the fact that Hae-won never bothered to reply."
Once Hae-woo arrives, she learns of Bok-nam's terrible fate -- to serve as a slave for the island's residents. When she realizes her daughter's destiny is going to be the same as her own, Bok-nam tries to escape, but her daughter is killed in the process -- thanks to "Hae-won's negligence". The grieving mother snaps, grabs a sickle and sets out for revenge.
The trailer looks very intriguing. No word on when this might turn up in the US -- but I'd bet someone like IFC would be willing to pick it up. Hop past the break to see the new clip for yourself.
