Based on stories which were later published as the Forsyth novel The Deceiver, there are six films, most with the themes of espionage and war. An important character who appears in all six is Sam McCready, a Secret Intelligence Service agent who has become an author but continues to work on SIS operations. He plays the lead in most of the films, but in A Little Piece of Sunshine he has more of a supporting role. Each of the stories are introduced on screen by Frederick Forsyth.
