Dead in a Heartbeat

Dead in a Heartbeat is a television film that was originally aired on TBS on March 3, 2002.

Later, Lt. Royko told Dr. Hayes to compile a list of exboyfriends or other people who are possible suspects. Lt. Royko told Dr. Hayes that originally she was a suspect but that her refusal to leave the operating room took her off the list of potential suspects.A cellular phone was found in a Federal Express package in Dr. Hayes office. The cellular phone was from the person planting the bombs. He gave the information about a flight which the next victim was a passenger. The cellular phone also displayed a number which was a countdown to when the bomb would explode. A hypothesis that Hayes and Royko had was that the count down was linked to the victims heartbeat. They also realized that as soon as the pacemaker was removed it would explode. Dr. Hayes suggested attaching it to a simulator so that it would still think it is attached to the heart. The next victim was Mr. Benjamin McDonald who was in the airport as Dr. Hayes and Lt. Royko showed up. Mr. McDonald was called to the desk and Dr. Hayes and Lt. Royko informed him that something was wrong with the pacemaker. They brought Mr. McDonald into a different room where they attempted to remove the pacemaker, assuring him that everything would be fine. Dr. Hayes had isolated the pacemaker and was ready to be removed but unfortunately, the simulator had not arrived in time. Lt. Royko was given a shield to sit behind while he cut the pacemaker from a distance. Mr. McDonalds last words were to tell his wife and children that he loved them. Right after Lt. Royko cut the pacemaker, it exploded. ........
