I admit to being a big fan of the darker, more adult, and explicit side of Joseph W. Sarno's filmography (Butterflies, Kärleksön, Fäbodjäntan…), so I take full responsibility for how disappointing this film was for me. While the plot includes several softcore sex scenes, some quite explicit, none actually reveal any objective titillation or show the most intimate secrets of the attractive protagonists. Eric Edwards plays an archaeology professor (I can't think of a less erotic profession for an essentially erotic plot) who spends a few days with his wife Laura (a fascinating Mary Mendum, also known as Rebecca Brooke) and his technical assistant Anna (the beautiful Cathja Graff, who could have been a sensational discovery in adult films, but who is so unremarkable that we'll never see her in any other role), collecting "stones" in a Swedish maritime environment for his "exciting" university studies. Anna not only admires the professor, but also begins a sexual and romantic affair with him behind his wife's back, while her wife sunbathes on the beach or visits friends in town. When she finally discovers everything, Anna plots a lesbian revenge that doesn't end as she expected.
