Mickey, who is intelligent but lacking ambition, is always hustling and looking for the next easy payday. It seems like her ship has finally come in when she goes to Greenwich Connecticut to visit her estranged sister and billionaire brother-in-law in search of a hand out, and they flee the country to avoid federal fraud charges, leaving her with everything. But nothing in life is free, and "everything" includes guardianship of her sisters three ill-mannered children-- 18-year-old Sabrina, 13-year-old future Republican Chip and fragile 7-year-old Ben. Though motherhood was never in her plans, Mickey discovers a little responsibility never hurt anybody.
