I am a movie director and I just received the following movie plot. Could you help me answer this question? If not, let me know by writing "Not answerable". Plot title: House of 1000 Corpses Movie plot: After an opening black-and-white segment of a TV horror host named Dr. Wolfenstein introducing a Halloween movie marathon, there is a TV commercial advertisement where a old redneck clown named Captain Spaulding (Sid Haig) introducing his tourist attraction, titled 'Captain Spaulding's Museum of Monsters and Madmen' which is a place featuring serial killer attractions and fried chicken, as well as decorated with oddities and collectables.At Captain Spaulding's Museum of Monsters and Madmen, it is a run-down gas station out in the middle of nowhere, near the small Texas town of Ruggsville. The date is October 30, 1977. The local sheriff is filling up his car while feeding his pet dog some fried chicken wings. Inside, Captain Spaulding is having a conversation with an old decrepit local man named Stucky (Michael J. Pollard) over a topless autographed photo of June Wilkinson and about the local simpleton who works down the road. When Stucky goes to the nearby restroom, two masked thugs break into the gas station/museum, who for some reason thought it was a good idea to rob a store obviously run by psychopaths. As the two men hold Stucky and Spaulding at gunpoint, the tough-talking lead thug, named Killer Karl, demands that Spaulding hand over the cash register, while the other thug, whom is clearly mentally retarded, holds Stucky back. Spaulding refuses to open the cash register, and with a gun pointed at his face, defiantly says things like "fuck yo Mama!" "fuck you sister!" to Killer Karl. Stucky seems to recognize the second robber as Richard Wick, the local simpleton who works down at the local hardware store. Suddenly, a third man comes crashing through the front door, dressed in overalls and wearing a gigantic clown helmet. He is clutching a mallet which he puts to good use by literally beating Killer Karl down, while Richard Wick panics and shoots off his gun, hitting Stucky, but missing Captain Spaulding who pulls out a gun of his own and shoots Richard in the head, killing him. Seeing that Killer Karl... My question: What is Denise tied to?
