"Nostromos," an obvious take on a famous name, is pictured here as a fake psychic out to bilk the money-men of Gotham. Nostromos is an ex-actor and small-time con man, and he has a big racket going on predicting the future. Of course, it helps when he does something to make sure that future event happens!
The guy is dressed with a mask and cape who likes a cross between the Devil and Dracula. Batman knows he's a fraud right away.
How to expose him as a fake? That's basically the storyline here in this episode. It's a fair episode - not really that much happening. Specifically, a bigwig named "Ethan Clarke" (William Windom) in the city is ready to give the guy millions, being duped by the charlatan and the old guy's daughter winds up as a hostage to make sure the sucker pays off. It's not as dramatic as I describe. The famous Heather Locklear voices the daughter, "Lisa."
