Directed by Massimo Dallamano and produced by Harry Alan Towers, the film stresses the decadence and eroticism of the story and changes the setting to early 1970s London.

Dorian sits with his friend Basil and another man, drinking in a London strip club.

Basil's client Henry Wotton arrives with his sister and wants the picture of Dorian Gray for his gallery.

It is soon revealed that, just as in Wilde's story that bears his name, Dorian's portrait ages in his place; he himself is still young and beautiful.

He collapses, and in death takes on the features of the older alter ego from the portrait, which shows him again as a handsome young man.
