Champagne, Sydney Dance, Lacy Rose and Asia Carrera want to make it big in the music biz. They've done a demo tape. Trouble is, the girls left the recorder running after they finished singing, and it caught them doing some extra-curricular harmonizing in the key of sex.

When record promoters Stephen St. Croix and Sean Michaels hear the tape, they're more impressed with the sounds of the four girls going at it than with the music — so the balance of the tape features the guys pairing off with the girls in different combinations, but not before Sydney takes on St. Croix and Michaels at once.

The lion's share of the rest of the tape is taken up with cross-cutting the sex scene between Carrera and St. Croix with the threeway featuring Champagne, Rose and Michaels. Unfortunately, the sex is about as flat as the girls' voices, and the rump-bumping is strictly by the numbers. Look for Carrera to make her name in better features, and market this in your interracial section.
