An all-star cast heads this drama about love, possession and obsession. Alex (Art Garfunkel) is an American psychoanalyst and lecturer in Vienna. He meets and falls in love with Milena (Theresa Russell), a young and beautiful American, and the two embark on a passionate affair. She, however, does not wish to be confined to one man, and as she becomes increasingly unfaithful, Alex becomes more and more possessive. The film is told in flashback as Alex sits in a hospital where Milena is being treated for a drug overdose. He recounts the events to the investigating officer (Harvey Keitel), who must decide whether her condition is attempted suicide or something more sinister.
