Soon after their arrival at the hotel, Disher is run down and seriously injured by a car belonging to one of Natalie's relatives, saved from death only by the suitcases he had been hauling. The only clues to the driver's identity are the red baseball cap Disher saw as the car came toward him and a bit of greenish mud on the car floor. The wedding photographer, meanwhile, has disappeared, and Captain Stottlemeyer goes undercover as his replacement, ordering Monk to come with him. Concerned that someone in her family may have attempted murder, Natalie convinces him to be her new date. When a man's body is discovered in one of the hotel's mud baths, Monk identifies the man as the photographer based on his stained fingers, and Stottlemeyer joins forces with the local police chief to obtain a search warrant and search the victim's home for clues. Meanwhile, Monk catches the bride-to-be in a lie about her parents' death in a plane crash in 1995. Could she be "the guy," or is the falsehood unconnected to the crimes? And what can be the link between the dead photographer and Disher?
