This is a story about love and obsession between Alex (Art Garfunkel) and Milena (Theresa Russell) who are living in Vienna. The movie was directed by the always interesting Nicolas Roeg. One of the promotional materials calls it a "terrifying love story" and that sums it up pretty well. In one brief scene we see Alex and Milena in Casablanca, Morroco, sitting at an outdoor cafe above a plaza where some snake charmers are playing instruments and dancing with snakes. Alex wants to plan their future and proposes marriage but Milena replies that she is happy with the way things are. As the conversation gets more and more uncomfortable the movie cuts between shots of snakes in the hands of the entertainers and shots of the couple, then it finally cuts to them leaving in an airplane.
The snakes are probably native to Morocco, where the scene was filmed. We see a cobra and some kind of viper, and a third snake. It's interesting to compare the techniques of the Moroccan snake charmers, who handle the snakes and hang them around their necks and dangle them over their heads, with Indian snake charmers, who mainly leave the snakes in a basket and play a flute to make it appear that the snakes are dancing to the music.
