Happily married to Josh and settled into the community of Cameron Valley, Molly has finally found her place. But waiting for the next step, aka a baby, is taking longer than expected. When Josh's teenage daughter, Sarah arrives, complete with heavy eye make-up and attitude, all baby-making plans are put on hold and Molly must throw herself into the role of step-mother. But playing happy families proves harder than expected when Sarah makes it clear that in the fight for alpha female... Molly will lose. Struggling to share Josh's happiness at his daughter's arrival, Molly finds support (and an avenue to vent) in the form of fellow floundering parent, Sam. Does it matter that he's good-looking and looks at her in a way that Josh hasn't since Sarah arrived? With tension rising at home as well as a heatwave that threatens the Cameron Valley Christmas Pageant, Molly must find a way to make this family work or risk losing it all.
