Wayne and Dahlia Malloy are Irish Travellers con artists and thieves who travel with their children Di Di (Delilah), Cael, and Sam. As the series begins, Dahlia has just been paroled from prison. During her two-year sentence, she developed various drug addictions. In her absence, Wayne and the children have been continuing to act as con artists across the U.S. After a brief reunion with their Traveller clan, the family flees to avoid an arranged marriage for Di Di. Wayne steals a large amount from the clan's hoard of cash, and the family runs off. After getting into an altercation and RV chase with another Traveller family, the Malloys are involved in a car accident that kills a very wealthy couple, the eponymous Riches. In the hopes of pursuing a "better life", they adopt the Riches' identities in an affluent gated community in Baton Rouge, Louisiana. They struggle to adjust to their new lives as buffers, as they call people who are not Travellers.

Josh Corman is an artist at heart but not by trade. Things haven’t been going his way lately — his lifelong dream of a career in music didn't pan out and he finds himself teaching fifth grade at a school in the San Fernando Valley, his ex-fiancé Megan has moved out and his high school buddy has moved in. Aware that he still has a lot to be thankful for, Josh struggles nevertheless through universal feelings of anxiety, loneliness and self-doubt. This relatable comedy-drama speaks for our contemporary generation of 30-somethings: rich with good intentions, poor with student loans, and working to become grown-ups sometime before they’re senior citizens.
