The female head of a detective agency is hired by a crime lord to figure out who's taking his action.
Johnnie Hill plays Velvet Smooth in this soft-core crime meller. The slinky Ms. Smooth is head of a private detective agency, specializing in protecting the unprotectable. Her current client is in deep with a murderous numbers racket. So Velvet Smooth goes undercover (and occasionally under covers) to smash the ring. An "R" rating hardly covers it.
