S1·E15 The Hit Parade

Danny goes undercover as an assassin, and is hired to whack two guys by Michael Pappas, a middleman for a number of higher-up criminals. Danny and Chance stage the ""hits"" and take the intended victims, Barrett and Gil, to an FBI safe house. Both claim no knowledge of anyone who would want them whacked, and deny having previously met one other. But it is soon revealed that they do know each other-and Pappas. The case turns out to be much bigger than originally realized: the three are responsible for the largest Brinks truck robbery ever, and have been trying to knock one another off ever since.
