Tony attends a political function with Vance and when he meets a Senator, the man walks away from him and when they're alone says something Tony finds odd and then hands him an envelope with ten thousand dollars in it. Later, Gibbs informs them that an NCIS agent was killed and when asked who he says Tony DiNozzo. They go there and see the man has false credentials and they surmise that the Senator Tony met is being blackmail by an agent Tony DiNozzo evidently, the man they found. But they later learn he was not the one who was blackmailing the Senator Tony met but was blackmailing another Senator. Another man who is also posing as Tony is the one who was blackmailing the Senator. And they discover another impostor who is blackmailing someone else. They all claim to have been hired by someone they never met. So they wonder how did they get Tony's credentials and who killed the Tony they found.
