A throwback to the Italian giallo films of the 1970s, "Blood Tulips" tells the story of Starla, a Los Angeles artist who travels to Amsterdam in search of her sister, Tess, who has been kidnapped, drugged and sold into the sex trade of the Red-Light District. Once in Holland, Starla meets a local actor named Oliver who helps her locate and rescue Tess from a brothel run by the sadistic Madam Reeks. But little do they know, the infamous Black Tulip Killer is hot on their trail and he will stop at nothing to cover his tracks.
