Cy and Lou head back to the mountains of Sevier County, Tennessee on vacation with no intention of becoming involved in a murder investigation. But they stumble upon a dead body with two envelopes on it, early in their vacation. One envelope is marked Lt. Dekker. The other says Local Police. Each envelope contains a small amount of information about the identity of the victim and the murderer and a clue as to where they are to go next. They are told they will be going to ten places in all, all in Pigeon Forge. They are led from one Pigeon Forge attraction to another, and at each one, they are to find someone with an envelope containing a clue as to where they are to go next. But the clues are not easy to figure out, and they must seek help among the locals and other vacationers, and that doesn't always go the way Cy hopes it will go. All of it adds up to a hilarious romp and an eventual conclusion.
