Rokugatsu no hebi

In an anonymous Japanese metropolis, a dark erotic force infiltrates the lives of a reserved career woman in her thirties and her obsessively clean workaholic husband. Invading the most private aspects of the couple′s lives, a mysterious stranger sends an envelope bearing the inscription "Your Husband′s Secrets." A deliriously perverse tale of buried sexual desires, Shinya Tsukamoto′s surreal journey to the dark side of obsession is as stylish as it is totally unforgettable. (texto oficial de la distribuidora)
