Lisa (Luigina Rocchi) is a young, attractive woman stuck in a sexually and emotionally unfulfilling marriage with a significantly older husband (Francesco Parisi). Seeking excitement beyond her tedious domestic life, Lisa initiates an extramarital affair with an older acquaintance, Engineer Boschi (Giovanni Di Benedetto), but remains dissatisfied. Her search for passion leads her to a wealthy acquaintance, The Count (Enzo Fisichella), who introduces her to Marco (Mario Cutini), a young stud, along with his lesbian playmates Carmen (Guia Lauri Filzi) and Patrizia (Maruska Ferretti). After engaging in a hedonistic group encounter, Lisa becomes fixated on Marco and seeks him out again, only to discover his aggressive and dangerous nature.
