Brutal Storm(1985)

Original title: Vahşet Kasırgası

Two sisters own the Gul Hotel in an idyllic village in the South of Turkey. During the summer the town is guested by tourists who don't really act in the conservative fashion that the sisters expect. Fearing that these loose and immoral tourists might spread their illness of decadence, the sisters start to clean up the riff raff in their own special way. Also known as "Brutal Storm"
