Mackenzie, aka Mickey, is an overbearing hustler from Rhode Island who lives an aimless life with no real responsibility. While visiting her estranged sister and wealthy brother-in-law in search of a handout, she is shocked when they flee the country to escape federal fraud charges.

As a result, Mickey is left to assume guardianship of the couple's three high-maintenance children. It's not all bad though, as with this added responsibility come some of the perks that she has always wanted, like the mansion with walk-in closet and the luxury car.

Can Mikey leave her irresponsible ways behind and adapt to her new life while transforming these spoiled kids into decent members of society?
