"Somewhere in the crowd is a killer who can turn smiles into screams."
A young terrorist kills and injures patrons of a Norfolk amusement park by placing homemade explosives on the track of one of its roller coasters. After staging a similar incident in Pittsburgh, he sends a tape to a meeting of major amusement park executives in Chicago, demanding $1 million to make him stop.
