One night, a thief fleeing through Georgetown (Washington, D.C.) in Washington, D.C., is shot by a man carrying a briefcase. A deliveryman who witnesses the incident is also shot by the killer and is left in a coma. The following morning, a young woman is killed by a Washington Metro train in what seems to be suicide. Congressman Stephen Collins is distraught to hear that the woman was Sonia Baker, a researcher on his staff. Collins, who has military experience, is leading an investigation into PointCorp, a private military company with controversial operations involving mercenary. Collins tells his college roommate and old friend Cal McAffrey, an investigative reporter, that he had been having an affair with Sonia and that she had sent him a cheerful video message on the morning of her death, which he says is inconsistent and unusual behavior for someone about to commit suicide.
