A British television anthology of stories, often with sinister and wryly comedic undertones, and a twist at the end. With early episodes written and presented by Roald Dahl, the series featured a plethora of big name guest stars.

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.

In the 26th century, the Doctor and Jo uncover a plot by the Master to provoke an interplanetary war between Earth and Draconia.
