Mackenzie The Mick Murphy 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.
When Mickey learns they've all forgotten Ben's seventh birthday, the family is forced to put their selfish tendencies aside for one day and throw him the celebration he deserves, which proves way harder than it sounds.
After Chip gets roped into a scandal, Sabrina leads a School Honor Board trial against him, where he must choose between snitching on his teammates or taking the fall. Meanwhile, Alba dents the family Bugatti, with Ben as a witness.
When it seems as though Chip is getting scammed by a girl he met online, Mickey tries to teach him how to be a "wolf" vs. a "sheep." Meanwhile, Sabrina is scared that her boyfriend is beginning to mirror Jimmy's ways and she plans an intervention.
Sabrina tells Mickey she wants to augment her figure, so Mickey decides the best way to dissuade her from doing so is to do a test-run in public. Meanwhile, Jimmy takes Chip and Ben to a baseball game to teach them how to be more masculine.
