Turks and Caicos, the second film in the Worricker Trilogy, surrounds Johnny Worricker after he has walked out of his job at M15, en route to the airport to choose his destination at random. A conspiracy to turn control of M15 over to the Prime Minister has led Worricker to the islands known as Turks and Caicos... but his presence on the obscure islands brings a new dilemma to light. It is here that the CIA persuades Worricker to deal with a group of ambiguous Americans attending a high-level conference regarding the world financial crisis. Meanwhile, an old girl-friend, Margot Tyrrell, is being asked to betray her boss in London in order to establish an illicit connection between the prime minister and dark goings-on in the war on terror.
