Harold is a former radio show host in his eighties not quite ready for his star to wane. Though the station he helped build has long since moved on without him in a new direction and with a new conservative talk show star, he's secretly planning his big return to the airwaves. Despite the odds and the changing taste of the public, Harold is developing a ventriloquist act along with his dummy sidekick and best friend, Lenny Schpilkus, in the spirit of Charlie McCarthy and the golden age of radio. Meanwhile, Harold's daughter, Eloise, is growing concerned for her aging father who, in spite all his childlike enthusiasm, seems no longer able to care for himself and a little too attached to his puppet companion.
