The focus of the film is purely on the sex scene, and Deodato made full use of the actress's assets to make a surprisingly pornographic thriller! The focus of the film is on three sisters (enough to attract themselves) who have to call the police when the body of a pimp named Yuri is found in the washing machine. But when the inspector arrived, the body disappeared-but it was a copper wire that could not easily put the box down, and after deciding to devote all his free time to the box and the three sisters concerned, he soon found himself part of their sex game.
