Self-dubbed the "Black Brady Bunch," this southern family integrates their strong religious conviction with their penchant for the finer things in life. Under the watchful eye of the patriarch and matriarch, the Tankard children, although grown-up, still live at home and must abide by Ben and Jewel's rules. With the belief that "God wants us all to be millionaires," the Tankards aim to be the best and brightest in everything they do. Along with their drive, comes a healthy dose of rivalry proving the adage, "You can choose your friends but you can't choose your family" especially true.
