Adam forgoes his weekly Mama-Schmoo dinner date to hang out with his new colleagues, which includes a new special lady. Beverly (Wendi McLendon-Covey) worried sick that Adam is running in too fast a crowd, pulls out the ultimate stop to end it all. Meanwhile, Barry (Troy Gentile) faces the harsh reality that medical school is tougher than anticipated.
It's Thanksgiving, and no one crushes Turkey Day like Beverly Goldberg; though, with the loss of Murray, this holiday feels a bit different. Geoff and Erica are stressed over the new baby; and, even more worrisome, an unexpected Goldberg relative arrives. With everyone highly suspicious of this unforeseen visitor, things are likely to go off the rails at any moment.
In homage to the classic Halloween movies of the '80s, Geoff's terror over Beverly controlling all baby-care duties turns into a jump-scare-filled comedic thriller. Meanwhile, Adam is excited to spend Halloween visiting Dave Kim at NYU; however, his feelings change when he discovers that Dave Kim has reinvented himself.
Despite promising to keep distance from Brea so they can each establish themselves at college, Adam calls her, sending Beverly into a tailspin. Meanwhile, Joanne lands a coveted job at a posh Philly law firm and Barry takes full advantage of the perks of her new gig, blinding him from the reality of the situation.
With both sides of the family eager for answers on Geoff and Erica's pregnancy, they decide to keep their baby's sex a surprise. However, a sonagram finding from Lou Schwartz might provide an unexpected discovery. Meanwhile, Adam recruits Glascott to help his mother cope with his departure for NYU; but when he later has a change of heart about heading off to college, he sources a job as the personal assistant to a special celebrity to help lessen the blow when news of his deferred enrollment is delivered to Beverly.
With everyone living back at home, the house is full of Goldberg chaos and also ... Goldberg stuff, which is driving pregnant Erica bonkers and leads her to enlist Beverly's help in clearing things out for the baby. Meanwhile, Adam and Barry are forced to share a bedroom to make room for the baby nursery. Adam can't handle how insufferable Barry is, so he comes up with the ultimate prank to get back at him.
