Alex Munn works in Manhattan's "Television City" as head writer for an ordinary soap opera. But when his TV bosses decide to use brand-new virtual reality technology to produce the most involving drama series ever, Munn signs on to revolutionize the TV industry. In his spare time, though, he creates another virtual world: "Munn's World." It's set in gaslit 1850s New York City, where a vicious serial killer called the Fishman is disemboweling victims in the Bowery. But now, something has gone terribly wrong. It's unscripted, it's terrifying, but the Fishman has somehow escaped from Munn's World--and followed Alex into the present.
