Mary is devasted that Halloween has been canceled by the city, so Darlene and Becky enlist Jackie and the rest of the family to create an unforgettable experience. Meanwhile, Mark goes toe-to-toe with another kid at school who doesn't believe in wearing a mask
Mark and Collin get into heated debates over probably nothing. Trick Or Treat is canceled, so The Conner Family have to throw a party for them, especially Mary ... who is getting ready to run away, and not be found.
Jackie walks in the kitchen to tell Dan and Darlene about bubble based Halloween costumes. Mary is a collectible doll. Mark is a gumball machine. They just found out that Trick Or Treat is canceled anyways, with Mary walking out angrily. Mark tells Dan that people get into arguments about wearing masks. Becky says that she can not find Mary. They look for her before she finds some body that is sick.
Darlene finds her on the roof and bonds with her. Mary tells Darlene that D.J. is no longer at home be cause he is away at work. While she is old enough to take care of herself, she still hates being by herself all the time. She is adamant to move in to the family house.
At Wellman, Darlene and Becky try to reach D.J. but his voice mail is full. They both agree that they bring Mary home with them.
Mark decided to start a fight with the other people, but gets suspended. Darlene finds out that Dan told him what to do about it. Jackie is even more supportive than Dan is. Darlene keeps talking to Mark and also says that they are going to have Mary with them tonight.
They go to Chicago, only to find out that everything is closed. But Becky tells them that they have a Trick Or Treat Party.
They open every door in the house. Darlene, Becky, Jackie, Ben, Harris, and Dan are in costumes. An Angry D.J. knocks on the door to bring Mary with him. Becky and Darlene tell them that Mary will stay with them or run away. He asks Mary if that is true. D.J. can only see Mary during his days off and is still upset that his walls crashed in on him.
Darlene confronts Dan about Mark's fight. He says that if Collin approached him with a debate he can talk back or even fight back. Darlene says it is pointless if Collin and his group is unreasonable. She also tells Dan that you can not quietly have a beer with your friends anymore. Dan says that one of the reasons why people are conflicted is because both Collin's parents and Darlene have raised them to be adversarial. Darlene says that it is much more complicated than that and the topics that people bicker about do not come from home. When Dan asks what else to do, she says that they have no choice but to trust politicians since they are supposed to be experts. When Darlene says that people don't get discouraged from voting, Dan says that The Government took away all the public mail boxes to hinder people from voting safely.
The closing segment has the adults playing poker with confiscated candy.
