Snatched Women (1971)
An unfortunate lady is marked for abduction by a gang of bumbling crooks. After getting confused about the correct target to kidnap, they end up snatching five random women off the street and hold them hostage at their safe house. While awaiting directions from the boss on how to fix the situation, the grimy bastards all take their turns violating the horrified ladies - starting out with the sole virgin among the group.
Snatched Women (aka The Snatch) is an obscure, bottom of the barrel, vintage porno starring Adam Ward, Jane Allyson, Dick Burns, and Jill Sweete. The film supposedly features Dyanne Thorne (the infamous Ilsa of Naziploitation fame) in her one and only hardcore sex scene. She is said to be the large chested lady in the film wearing the pink mini-dress and ridiculous wig. The film is listed in her filmography on the Internet Movie Database and Wikipedia, even though there are many who say it isn't her.
