Research librarian Elana Fabrizzio was in the wrong place at the wrong time. While working her late night shift at the library, she overhears a man hire a mercenary to kill Keely Walsh-Maddox and other Security Specialists International operatives. Things go from bad to worse when the man kills a student and a security guard on his way out of the library. SSI operative Vanko Petriv is in New York City on holiday and is redirected to Washington, D.C. to become Elana's personal security. Turns out the man she overheard is the traitor SSI has been pursuing for quite a while. Her eyewitness testimony would eliminate the treacherous thorn in SSI's side and rid the intelligence community of a traitor once and for all.
