Red Rings of Fear (Italian: Enigma rosso, German: Orgie des Todes, Spanish: Tráfico de menores) is a 1978 giallo film directed by Alberto Negrin.

[2][3] A detective investigates the killing of a teenage girl and turns his suspicions on three girlfriends of the victim, who dub themselves "The Inseparables."

Red Rings of Fear is the third entry in a loosely linked series of film called the Schoolgirls in Peril trilogy,[4] a series of films based on the sexual exploits of young girls and their reaction to the adults.

[1] In a contemporary review, Paul Taylor (Monthly Film Bulletin) gave the film a negative review, calling it "a wholly inane and incoherent thriller, which scarcely seems to have benefited form the attentions of no less than six credited screenwriters."

and that it featured a "bored-looking Fabio Testi, when not shooting gratuitous fill-ins (schoolgirls in the showers; an abortion sequence) from silly angles, Negrin peppers the proceedings with would-be enigmatic close-ups of car radiator grilles, a madonna statue and a watching eye, plus titillating flashbacks to the fatal party"[8]
