Cannon investigates a doctors claim that he is innocent of a death he was charged with concerning a patient he was treating that had slipped into a diabetic coma. Cannon becomes involved in a medical malpractice suit when a young resident physician is charged with making the wrong diagnosis on a woman in an apparent diabetic coma who dies after his treatment. Hired by the hospital facing a two million dollar suit, Cannon hears testimony of the accused Dr. Jeff Reston, played by guest star David Birney, that the woman he treated wore a diabetic's bracelet. She was, in fact, suffering from hypoglycemia. But the bracelet disappeared and none of the nurses attending with Reston can back up his story. Reston then gives Cannon a motive for a possible conspiracy against him.
