Psych (2006)

S4E3 High Noon-ish

Lassiter hesitantly reaches out to Shawn and Gus when his surrogate father, the sheriff of Sonora, becomes convinced that a ghost is causing chaos in his town. Although this Wild West-themed town is more about entertainment than reality, it quickly becomes evident that a genuine crime is in the works, with the murder of the sheriff's business rival just the start of a larger plot.
