When DeDe drops by unexpectedly, Mitchell and Cam come to a realization about her effect on their lives. Phil, Luke, Alex and Haley all have different bad news to break to Claire and compete about who to go first in the tiny window of time after her monthly spa day, when she's at her most relaxed. Gloria organises a premiere for Jay and Manny’s horror movie at the Pritchett home for the whole family.
DeDe drops by at Mitch and Cam's place, revealing that she and Cam have maintained an acquaintance behind Mitch’s back, to his sheer horror. Cam, as always, annoyingly justifies his selfish act by manipulating the situation to make it seem that Mitchell is the selfish one for freaking out over their friendship, until he realises that Mitch is right: DeDe is using him to control her son’s life.
Phil and the kids try to deliver different bad news to Claire when she is in an exceptionally good mood, but fail when they panic and mess up the order in which they are supposed to go.
Jay is helping Manny edit his debut movie, a horror movie in which Phil has a small role. While Gloria busies herself with setting up the house for the premiere, the two discover that the sounds of the monster they created resembles angry noises made by Gloria. They scramble to hide this knowledge from her.
After the movie screening, tensions boil over as the family confronts DeDe, but Claire surprisingly comes to her rescue, while Gloria, who has found out what Jay and Manny have been trying to hide from her, comes to Claire’s rescue. They accuse their family of “transforming mothers into monsters”, at which point Phil steps in to deliver a few touching lines about the monster/mother parallel that closely resemble his lines in the film that had been cut.
As the family reconciles with their mother figures, Jay and Manny muse that if Phil had understood his script the way he delivered the lines just now, they would not have cut out his scene.
