One on Top of the Other, also known as Perversion Story, is a 1969 giallo film directed by Lucio Fulci. Written by Fulci and Roberto Gianviti, the film stars Jean Sorel, Marisa Mell, Elsa Martinelli, Alberto de Mendoza and John Ireland. The first giallo directed by Fulci, its plot concerns George Dummurrier (Sorel), an unscrupulous San Franciscan doctor who is suspected of orchestrating the death of his asthmatic wife Susan (Mell) as part of an insurance scam, despite her seeming reemergence as Monica Weston, a high-class stripper.
