Father Henry Stephens goes missing from his church after returning from the scene of a road accident, during which he gave Last Rites to a dying woman. When the FBI agents arrive, they speculate on the reasons for the disappearance, including Henry's declining health from cirrhosis of the liver and his state of mind following the accident. However, when Vivian is told that a doner liver has been found for Henry, the search for the missing man becomes increasingly urgent. During the investigation, the team find a large stash of money in Henry's apartment that has traces of drugs on it, and when it is discovered that he had contact with a man recently released from prison, it appears that Henry may not have been the man of virtue that he first appeared. Some clever detective work by Samantha, confined to desk work after a shooting incident in the previous episode, provides an insight into the Father's background and the other members of the team must race against time to follow up the information and find the missing man.
