When Maddy finds a pregnancy test, she is convinced it belongs to one of her stepchildren. But the identity of its true owner comes as a big surprise.

In the aftermath of the family move, the cat has vanished, half their possessions are missing, and a crate is doubling as the baby's cot. In the middle of it all, Maddy and Jim struggle to get used to their new house, their new neighbours, and each other's children.

Maddy's husband Jim decides that her ex-husband Robbie is his new best friend. While the two of them bond by putting up shelves, Maddy's stepson decides to come out of the closet.

Maddy's stepdaughter Katy becomes a vegetarian, but her animal rights stance only leads to animal wrongs. Meanwhile, Danny gets an unconventional job.
