After returning to the family-run theater where he first discovered his talent, he finds his father, the former artistic director, suffering from dementia. The theater, now reduced to a dinner theater serving murder mysteries, is run by his brother (Tenney) and sister-in-law, who is also the town’s mayor. Determined to restore the theater’s former glory, Richard plans to stage a great American classic, with himself as director and star, in an effort to save both the theater and the town.
