"In a small town in Japan, Kirie comes upon her boyfriend's father silently videotaping a snail. He seems unaware of her presence and she thinks no more of it. Later, the mans obsession with spirals becomes more and more bizarre, ending in his suicide in a washing machine which turn his body into a spiral. Soon other inhabitants become possesed with different forms of spirals, one student seems to be mutating into a snail, another's hair becomes strangely medusa-like. The entire town becomes possesed."
This is a really cool Japanese comedy/horror, its very original to say the least but dont go into this one expecting a scare because that probably wont happen, worth mentioning the film is based on a manga so has a trippy look about it.
