Dwayne Wilson, a new recruit, joins the team to aid in a bank robbery at Quantico. Rudy Vittorio, a security guard was shot and killed. The team initially thinks that his death was the result of collateral damages that occurred during the robbery but when the getaway vehicle gets torched with all of the money inside, the robbery motive changes.
Dwayne and Tony find out that there was a similar robbery that occurred six months prior at a jewelry store where millions of dollars worth of diamonds were stolen. Joey Vittorio, the security guard victim's son, was one of the robbers. He had gone off with the diamonds and had been living underground in order to keep it all to himself. Joey's bank robber team had staged the bank robbery at the bank in order to kill Joey's dad and lure him to his funeral so that they could kidnap him and take their diamonds back.
Gibbs and the team go to the funeral late but with the new recruit, Wilson's help, they are able to catch Joey and all of the robbers. Director Vance asks Gibbs what he thinks about Wilson and he starts to think about Agent Langer, his previous recruit who ended up being a mole. Gibbs has a brief encounter with Agent Lee and becomes suspicious of her as an agent.
