At a chic nightclub for jaded jetsetters, a simulated snuff performance is the main attraction, and Lorna, its leading lady, is the obsession of men and women alike. Little do they realize that Lorna's Mephistophelean manager has transformed her into "the essence of evil... a devil on earth!" Soon the sensuous starlet's stage persona possesses her entirely, thrusting Lorna into a hallucinatory world of sadomasochistic excess and drawing everyone she touches into her debaucherous delirium. Can anyone stop Lorna before her perverse stage show becomes a murderous reality?
