 Saturday-night-special handguns are flooding the streets of New York City, and a check finds that they are being bought in South Carolina, where (at the time) there were no restrictions on gun sales. Eischied sends an undercover agent to the Palmetto State to look at a group of gun buyers who are buying the guns in bulk and reselling them for profit, but she witnesses the murder of another agent and Eischied must try to rescue her before her cover is blown.
