William McClusky (Sam Waterston) is a dashing and eccentric Scotsman whose charms rapidly overwhelm the sweet and naive Ann Walton (Jenny Agutter), but she nearly as quickly begins to comprehend that her new beau is anything but a one-woman man. In addition to his two ex-wives, with whom he remains remarkably close, William exhibits a disturbing attraction for nearly any female who crosses his path -- Ann's friends among them.

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.
