6 Days Dark (2015) takes an ancient Israeli superstition—that insanity occurs when one of God's commandment is broken—and uses a viscerally searing literal interpretation in modern times. Tanja is a beautiful young woman who makes the mistake of sleeping with an older married man. When his wife finds out, she puts a gypsy curse on Tanja that will send her deep into the hell of her own mind. For six days and six nights, she's tormented by waking nightmares that sink her slowly into darkness until her very existence is threatened. Luckily, both regular Tanja (Svetlana D. Petkovic) and dark Tanja (Ana Maljević) bare breasts while they sex up a lucky dude, and we get a glimpse of Jovana Puzavak and Sandra Jankovic making out in their lingerie in a castle!
