Mackenzie The Mick Molng is a brash, blue collar, two-bit hustler who has spent her entire life gaming the system and shirking any semblance of responsibility. But when her estranged sister and billionaire brother-in-law flee the country to escape federal charges, the opulent, care-free life Mickey has always envied is finally within reach… But there is one minor catch: she must assume custody of her sister's three rich, entitled, high-maintenance children.
Mickey and the kids are forced to downgrade from their temporary residence at a hotel after their financial advisor cuts them off due to excessive spending. Mickey and Sabrina refuse to accept the decision and launder up a plan to prevent anyone from stopping their stride. Meanwhile, Jimmy teaches Chip that the tricks to living in a luxurious hotel can be simple.
Mickey's relationship with Alba is tested when Greenwich divorcee Trish hits rock bottom and becomes the perfect new friend for Mickey. When Mickey sends Jimmy over to help Trish with some home repairs, she begins to question just how casual her relationship with him really is. Meanwhile, Sabrina and Ben take a shot at Chip's ego.
Mickey takes Sabrina to visit her mother in jail to gain closure, but it turns out Mickey may be the one who needs it the most. While visiting his father, Chip learns that he is in danger behind bars and enlists Jimmy for help. Meanwhile, Ben inadvertently distracts the bullies.
Mickey and Jimmy throw a Halloween party in their spooky, charred mansion but things get out of hand. Sabrina hopes to use the house party to cement her legacy, which her parents have tarnished, and Mickey teaches some pranksters a lesson.
When Mickey finds out Ben takes medication to keep him focused, she is determined to prove that he is a perfectly functioning kid without it. She and Alba take over his struggling science fair project, but become overly invested, while Jimmy helps Chip make his secret boys club cool again.
