The only mystery here is why the credits would claim that this is the largest cast of girls ever assembled. Anybody ever hear of Bruce Seven? How about Jim Holliday?
The mystery of the title, however, is who murdered Brooke Waters? She's the lover of Sarah-Jane Hamilton, who suspects that Brooke has been unfaithful — and sure enough, Sarah catches Brooke on tape, dallying with Tammi Ann. After that, we get cops (Sukoya, Coxx, Martyn) screwing each other, and the tape ends with Sarah in jail doing a fiveway with her cellmates (Newhart, Kiss, Saki and one of the newcomers).
The action here is passable, with no real standouts. Even Sarah-Jane doesn't give out with the enthusiasm that she had as the hostess of the Love Bunnies series. The positive qualities here are seeing old faces (Sukoya, Kiss) again, and the three new girls. Retailers should gauge their success with all-girl product and tapes featuring new faces, and order accordingly.
