More so than that of any foreign power, the information they gathered turned the tide against the insurgency, paving the way to the killing of ISIS leader Abu Bakr al-Baghdadi in 2019. Against the backdrop of the most brutal conflict of recent decades, we chart the spymaster's struggle to develop the unit from scratch in challenging circumstances after the American invasion of Iraq in 2003, we follow the fraught relationship of two of his agents, the al-Sudani brothers - one undercover in ISIS for sixteen long months, the other his handler - and we track a disillusioned scientist as she turns bomb-maker, threatening the lives of thousands.
