Please answer the following question: Generate a question about the following movie plot: Prologue[edit] A delivery truck pulls up to a newsstand in a small town where a young boy named Billy (named after and confused with the boy from Creepshow) arrives eagerly waiting for it. The truck's back shutter opens to reveal a sinister figure who drops off a package onto the sidewalk the latest issue of Creepshow, much to Billy's delight. As the film momentarily turns into an animation, the package opens of its own accord, (revealing the cover of the comic is the same as the cover in the final scene of the previous film). As Billy begins to read, the delivery man reveals his true identity as the Creepshow Creep. Old Chief Wood'nhead[edit] An elderly couple named Ray and Martha Spruce (Kennedy and Lamour) in a small, fictional, southwestern town called Dead River, oversee a general goods store whose decor includes a cigar store Indian named "Old Chief Wood'nhead" (Dan Kamin) on the front porch. They are humbled to see their old, run-down town coming to a bitter end. The Spruces are then visited by a Native American elder named Benjamin Whitemoon from a local tribe who gives them turquoise jewellery, which are his tribe's sacred treasures, as collateral for the debt the tribe has incurred. The elder bids them and Old Chief Wood'nhead (who nods to him, briefly startling him) farewell and returns to his tribe. Later that night, the Spruces are subject to a vicious robbery led by Benjamin's estranged nephew, Sam (Holt McCallany) armed with a shotgun, and his two friends, Andy and Fatstuff. After ransacking the store, Sam demands that Ray hand over the turquoise. The Spruces refuse, and are fatally shot by Sam. The three thugs then leave in their car and begin preparations to run away to Hollywood, California, where the vain Sam expects to become a movie star, in part due to his long, dark hair. Old Chief Wood'nhead then comes to life after they leave, and goes out on a vicious warpath to kill them and avenge the murdered Spruces. After brutally killing Fatstuff and Andy, Old Chief Wood'nhead corners Sam...
