Six days ago Sam returned to Sudan to work with a CIA task force, looking into the presence of the Al-Qaeda there; since then unknown people have tortured and killed two CIA agents near Khartoum, the capital, and the agency has lost contact with Sam; a third unidentified body, matching that of Sam, has turned up; Hetty agrees that a mole appears to be inside the CIA. G grabs his bag and goes to Khartoum, where he sees the charred body and reports to Hetty, saying that it's that of Michael Saleh (from a previous story); G meets a new friend and fellow inquirer; G meets Sam, and they go to work. Meanwhile back at home Kensi and Deeks have a frustrating conversation with a CIA guy. Sam receives two interesting invitations and deals with them; Kensi and Deeks find the mole and deal with it; Sam runs into bad trouble, but G helps greatly. G and Sam return to the US and take a third person with them.
