Based loosely on Milovan Glišić's classic 1880 Serbian vampire story After Ninety Years, Djordje Kadijevic's adaptation is a subversive, darkly erotic take on the pastoral tale of a group of rural villagers beset upon by the infamous vampire Sava Savanovic, who has killed all the local millers in succession, leaving an opening for young Strahinja, who is desperate for a way to win approval to marry the beautiful daughter of the village's wealthiest landowner. But is he prepared for the deadly secret of the She-Butterfly? Kadijevic takes dramatic license with the original story but retains the hypnotic day-to-day of a remote village steeped in superstition and boredom.
