When Jennie drags unfaithful hubby Michael from the city to a country house once owned by a murdered turn-of-the-century Artist, boorish Michael is bored and watches TV. But Jennie's not bored, because she finds some old, old sketches of a girl-in-white in the attic and has a dress made to match the sketch. And, shezam, when Jennie puts on that old-timey dress and wears her hair ""piled atop her head,"" not only does she look ""like Julie Christie in The Go-Between"" but she also gets headaches, has visions, and, double-shezam, goes a-time-travelin', ""happy to be back in 1899 again."" Back in 1899--away from her husband and her shrink, who quite naturally think she's gonzo--Jennie dallies passionately with the Artist but is terrified because she knows he'll be murdered (perhaps because of her--she's the girl in the sketch!) unless she can Change the Past. Only the most Twilight-Zone-prone will worry their stars over this one. The rest of us will be more shook up over the real question: since Jennie constantly has to wear the ""magic dress"" and ""it's much too precious to let out of her sight,"" when, for her Artist's sake if not that of the general populace, does she wash it?
