When a car rams through a guardrail and plunges into the river below, all the elements of a tantalizing movie thriller bubble to the surface: a drowned cocktail waitress, a disoriented driver with no memory of the accident -- and a ferocious D.A. who'll stop at nothing to prove him guilty. Add to that a touch of blackmail, some creepy red herrings and an acid-tongued lawyer and you get an intricate crime drama loaded with twists, turns and a startling conclusion to leave you breathless. Fresh off their scintillating teamwork on The Carpetbaggers, George Peppard and Elizabeth Ashley head a formidable cast -- including Roddy McDowall, Sally Kellerman (her second movie) and Herbert Marshall (his final movie) -- under the taut direction of Jack Smight (Harper, No Way to Treat a Lady).
