Plot summary
Lincoln receives a coded message from Michael asking them to find the "Sheik of Light." Sheba, the contact, agrees to help decode the message in exchange for money. Sara receives the video recording of Michael and meets up with Kellerman at the State Department. He deduces that Michael was the mastermind behind changing his identity. Later, he sends Sara footage of Michael killing a CIA deputy director. Michael acquires pills to give to his cellmate, Ja, who is suffering from withdrawals in exchange for a cell phone and credit card, using them to send a message to Sara.
Lincoln's team discovers that Mohammad El-Tunis, the Sheik, is a local electrical engineer trapped in an ISIL-controlled suburb with his daughter. They rescue the duo; and Mohammad is revealed to be the father of Sid, Michael's cellmate incarcerated for homosexuality. Mohammad gives Michael's team a signal to reveal that the escape plan is on. Sara receives Michael's message to get everyone to safety because "a storm is coming". The solitary inmates, including local ISIL leader Abu Ramal, are released into the general sector. Ramal and Michael are revealed to be friends.
