Set in a seedy Atlantic City casino that caters to aging baby boomers trying to re-live the 60s, The Prancing Horse centers around three of the younger casino regulars, a compulsive gambling New York surgeon, a misguided showgirl and a hooker with a beleaguered dream. The possibility that each of them can change one another's lives for the better comes into play as they share their stories in the casino bar in front of an amiable bartender with a few problems of his own.
