The Malloys are a distantly ethnic Irish/Gypsy family of traveling con artists (called 'Travlers') which make up of the patriarch Wayne, his jail bird wife Dahlia, and their three children/con-artists-in-training; headstrong Di Di, troubled Cael, and the cross-dressing Sam. After Dahlia is paroled from prison for serving time for petty robbery and larceny, Wayne tries to get money through his cousin Dale who lives at a Traveler's camp, but gets turned down. After ripping off Dale and his family, the Malloys take to the road in their RV trailer when, through a set of unusual circumstances, they witness a car accident and out of the blue, Wayne gets the family to assume the identities of the victim family, the Riches. The Malloys, posing as the Riches, move into a wealthy suburban neighborhood located in Louisiana, only to find that a glamorous life of settling down entails more than they expected.
