Will is thrilled to throw the first-grade parent social so that he can use this event to springboard his anti-smartphone platform to get parents to wait to buy their kids cellphones until eighth grade. He ropes his new love interest, Dr. Dewan, into helping him, but his plan doesn't work out quite like he had hoped. Douglas offers to have the social at his house so he can exact revenge on his rival dermatologist, Mark, whom Douglas is convinced stole his prized pen.

Seeing that baby Jack is about to walk for the first time, Miggy feels old and tries to recapture his youth by throwing an epic party. When the party doesn't go as expected, he insists that Poppy and Douglas stick around to help him. Angie's boyfriend, Owen, meets Graham for the first time, which doesn't go as well as they had hoped. When Will gets an opportunity to do the weather at 10:00 p.m., Rory tags along and causes drama on the set.

When the smooth-talking ladies' man, Xander, from Angie's one night stand turns out to be connected to the group in an unexpected way, she starts spiraling. Douglas is forced to confront some family issues with a little help from Poppy. Meanwhile, Will attempts to teach Miggy how to work on his disciplining skills as a parent, but Sophie, Rory and Graham make it anything but easy on him.
