All you need is love. All you get is sex . . . the saying is all too true in the strange private lives revealed in "Greetings from the Vodka Sea."A prim English bride honeymooning beside the Vodka Sea learns first-hand about drinking the water in foreign parts. A naive doctor and his wife diverge in a group sex session masquerading as therapy. A man with a past plots to seduce a deteriorated middle-aged woman who could expose him. Paths cross, whether by accident or by design. Life's randomness is offset by dark comedy, the dream-logic of fantasy, and an eerily familiar synchronicity.
