The late 1970s and early 1980s marked the zenith of an era when adult feature films were shot on 35mm film, featured narrative plots, and screened in mainstream theaters. At the absolute pinnacle of this cinematic movement stands Taboo (1980) , directed by Kirdy Stevens. Propelled by a definitive performance by British-born actress Kay Parker , the movie completely disrupted the landscape of adult entertainment.

The plot of Taboo is, on its surface, simple: A middle-aged woman (Parker, as "Barbara Scott") feels neglected by her husband and finds herself caught in a web of desire that leads to an intimate relationship with her own son (played by Mike Ranger).
