Spooks

Section D of MI5 is on the case when a car bomb detonates in Liverpool, killing family planning doctor Sarah Lynott (Karen Westwood). The agents determine that it is the work of an extremist pro-life movement, led by American terrorist Mary Kane (Lisa Eichhorn), who smuggled herself and 20 bombs into the country to set up cells. Zoe Reynolds (Keeley Hawes) poses as a sympathiser, and learns of Kane's next intended target. Zoe then poses as the target, Diane Sullivan, and lures Kane to a trap, and she is arrested. After Kane informs team leader Tom Quinn (Matthew Macfadyen) of the location of every cell she set up in the United Kingdom, he sends her to the Central Intelligence Agency (CIA), which returns her to Florida to be executed. Meanwhile, Tom enters a relationship with a civilian, Ellie Simm (Esther Hall) after an unrelated operation, going under the pseudonym Matthew Archer, a civil servant.
