The Unit
Episode 5
S1 E5:
Sala Al Gareb commits suicide inside the isolated prison cell where he has been confined. As far as Carla's bosses are concerned, his death probably means the end of a complex and uncomfortable situation. However, Carla thinks that there might be a subtle, pre-planned purpose behind his suicide. She thus discovers that Al Garheeb was able to get in touch thanks to his lawyer, with other convicts that sympathized with the Islamists' cause before he took his own life. Accordingly, all suspicious inmates are isolated. But by then, some of them have already been released from prison. Miriam finally succeeds in setting up a meeting with the informer of the CIA who had seen Al Garheeb in Nigeria. She flies to Lagos where she meets the man in question: William, an arms dealer.
