One of Sam's aliases receives an e-mail message from Abdul Habaza, who in a previous episode flew back to Yemen. Hetty and the rest of the team hope that Abdul will eventually lead them to Saadat, Abdul's brother, believed to be the leader of the Warriors of Islam. Sam finds a dead body, a fake passport, and a one-way ticket to Yemen, so he (with G as backup) goes back undercover and to Yemen, where G meets Nate, and Sam meets Abdul, who promptly moves Sam; G tails them. Along the way Sam passes a test, but another man does not; Sam takes charge of a 7-year-old boy, who is a hostage and a son of a Saudi prince. Meanwhile Kensi and Deeks find Saadat, Abdul's brother, in West Hollywood; Nell suggests that Abdul is the leader of the Warriors of Islam, who have issued a deadline for a hostage exchange. However, the team conclude that a trap awaits in Yemen; G and Sam, with support, work out everything and return the hostage to his father.
