Summer in Dover 1919: Christine's mother runs a boarding house, in which Christine feels like the dull aspidistras which clutter the rooms, until Captain Blaine arrives to find rooms for his rich aunt.

Jack Regan, an unethical officer of the Flying Squad, uses unorthodox methods to pursue criminals with the help of his partner, George Carter.

The lives of Bodie and Doyle, top agents for Britain's CI5 (Criminal Intelligence 5), and their controller, George Cowley. The mandate of CI5 was to fight terrorism and similar high-profile crimes. Cowley, a hard ex-MI5 operative, hand-picked each of his men. Bodie is a cynical ex-SAS paratrooper and mercenary whose nature ran to controlled violence, while his partner, Doyle, comes to CI5 from the regular police force, and is more of an open minded liberal. Their relationship is often contentious, but they are the top men in their field, and the ones to whom Cowley always assigned to the toughest cases.
