LOST AT SEA: A 1947 honeymoon voyage becomes a Hitchcock-style ordeal for a jittery heiress in "Treacherous Crossing." The so-so psychological thriller, premiering at 8 tonight on the USA cable channel, stars TV movie queen Lindsay Wagner as an abandoned bride aboard a luxurious ocean liner. Chic period costumes worn by Wagner and co-star Angie Dickinson compensate for the seasick camera angles and a leaky plot involving suicide, madness and murder. USA will rock the boat again at 8 p.m. Sunday and 1 p.m. April 18.
