 Diabetic ex-con Martin Haggard is abducted by two former cellmates who have been ordered to prevent him from testifying in the trial of his former syndicate boss. They lock him in a shed in a remote area, knowing that he will suffer a fatal diabetic shock within hours if he is unable to obtain his insulin. Haggard s frantic wife contacts the Highway Patrol and Dan Mathews and his officers race to find him in time while the uncooperative abductors watch with sadistic glee.
