On leave from CI5 with a hand injury, Bodie takes a day trip with his girlfriend and finds himself face-to-face with the leader of a terrorist group. He captures him but then the rest of the gang arrive and trap Bodie and his girlfriend in a nearby vicarage, leaving him unable to alert his colleagues back at CI5 HQ. With barely any clues as to his whereabouts, Doyle and Cowley go on a chase through the countryside to try and locate Bodie.
