In the Los Angeles of the future, police are forbidden to carry weapons and must use stun guns instead. A maverick detective ignores those restrictions in his pursuit of "The Bullseye Murderer," a psychotic rapist who takes a new drug called "Umbra" that gives him superhuman strength and intelligence.

This is a compilation by Mike Hunter (Gerd Wasmund) of vignettes linked with segments from a sex scene and a scene where a number of women or girls are sitting round at what turns out to be a sex club, reminiscing about their experiences which form the vignettes thus linked together. These vignettes were filmed by Lasse Braun in England in 1977 and had a separate existence as loops, sometimes in one or more different edits, but the compilation followed quickly as the women in the link sections also appear in the vignettes looking very similar.
