Jeffrey Hatcher’s 1998 play is based on an offbeat Twilight Zone-like premise: a mysterious woman in her early 30s, perhaps a Titanic survivor, is found nearly a century after the great ship sank. But Hatcher never manages to spin this premise into an interesting story. Instead he records in minute detail the various ways a secondary character, the obsessed grandson of one of the worthies killed on the Titanic, tries to prove the woman is a fraud. Worse, the dialogue is flat and the story’s turns are either painfully predictable or completely improbable. Director Ben Fuschen tries to give the show the illusion of depth with video effects. But all this eye candy can’t hide the script’s basic inertness. Flat performances don’t help. –Jack Helbig a Through 5/27: Thu-Sat 8 PM, Sun 7 PM, Oracle Productions, 3809 N.
