NANCY HITS A CHICAGO HOT SPOT WHERE CRIME IS REALLY COOKING! Nancy, Bess, and George have come to the city for a weekend of shopping and a night out at Reverb, the trendy new restaurant owned by Adam Sledge, lead singer of the chart-busting band Void. The place is the coolest thing going, packed with celebs and pulsating with excitement -- a wild scene that gets even wilder when a smoke bomb goes off. Behind the scenes, Nancy turns up a slew of suspects and all the ingredients for danger: jealousy, greed, and revenge. But perhaps most dangerous of all is Adam Sledge. The rock star's putting all the moves on Nancy, and he's proving a major distraction. If she fails to focus on the investigation, someone could get seriously hurt...including her!
