Blood Orgy of the Leather Girls is a 1988 horror film directed by Meredith Lucas and starring Robin Gingold, Jo Ann Wyman, and Dale Soules.
The film is narrated by a detective, Joe Morton, who has "been working for the Greater Planceville Police Department for 30 years".
Sarah, the leader of the gang, is an Adolf Hitler-idolizing, Iron Cross wearing, society- and life-hating Jewish teenager.
At the dance, Dorothea is found collapsed on the floor, and the remaining three girls spend the rest of the film hunting down and exacting their revenge on the perpetrators.
Blood Orgy of the Leather Girls was filmed during the 1980s in California, where the Lucases and David Nudelman lived.
Director Meredith Lucas was unable to find distribution for the film and, having no way to reconcile her debts, committed suicide.
Note that the contents of the official soundtrack differ greatly from the songs found in the actual film.
