Bloody Aria (Korean), A

On a day trip through the countryside, an aspiring opera singer flees to the woods to escape the advances of her lecherous professor and mentor. When a seemingly harmless local man offers her a ride to the bus station, she thinks she's been saved - until he insists that they stop to meet his friends, a disturbed group of country-bred thugs. She soon finds herself reunited with her teacher and it slowly becomes clear that the pair is being held captive to participate in the gang's sadistic mind games.
