Joe wants Mel to stop taking birth control so they can start a family, but she's unsure. So he invites Nate (guest star Ian Reed Kesler) and Gillian (guest star Tamera Mowry) over with their new baby to see if he can change her mind.
Meanwhile, Lennox tries to help Zander (guest star Sterling Knight) move on by setting him up with her friend Lilah (guest star Ayla Kell), and Ryder announces his unexpected plans for the future.
Melissa is a grown-up former wild child of a political family who is now a local politician herself. When her sister ends up in prison and brother-in-law flees after a scandal hits, Mel must take responsibility for her teenaged niece Lennox and pre-adolescent nephew Ryder. Spread too thin to manage by herself, help comes in the unlikely form of Joe who, desperate for a job, moves in and becomes the family's manny.
