Crissy Dowling passes her days by the pool in a private cabana, she splurges on ice cream but never gains an ounce, and each evening she transforms into a Princess, performing her musical cabaret inspired by the life of the late Diana Spencer. Some might find her strange or even delusional, an American speaking with a British accent, hair feathered into a style thirty years old, living and working in a casino that has become a dated trash heap. On top of that, Crissy's daily diet of Adderall and Valium leaves her more than a little tipsy, her Senator boyfriend has gone back to his wife, and her entire career rests on resembling a dead woman. But when Crissy's sister, Betsy, arrives in town with a new boyfriend and a teenage daughter, and when the owner of the Buckingham Palace Casino, is savagely murdered, Crissy's carefully constructed kingdom comes crashing down all around her.
