It’s five years since we last saw the Worsleys, with Paul and Ally on the verge of splitting, and Jim and Jackie in turmoil. Things are no less dramatic now as Luke and girlfriend Maya drop a bombshell at Christmas dinner that will change everyone’s lives forever.

After an apparent reconciliation with Ally, Paul's rage returns with a vengeance when he realizes that Ava has done something that could ruin her life. Luke and Jacob reunite, but things are becoming more complicated.

A calendar mix-up turns Paul and Ally’s fun night out into a stressful night in. A happy Ava finds her mood changing as the evening progresses. Luke turns up with an unwelcome friend and Carl finally sees the inside of the Worsley’s house.

A chat with Darren and a chance encounter convince Ally she needs more friends, so she decides to reunite her antenatal class. Ally tells Luke and Ava this was a friendship group with no arseholes. But 17 years is a long time.

Paul and Ally rush to fly back from their holiday when they hear that Maya is giving birth five weeks early. Ava and Sunil try to help Luke step up and become a father, but everyone is in shock when complications set in.

Luke’s condition worsens and he is admitted to a specialist pediatric unit. As Paul, Ally and their parents desperately wait for news, stress and fear cause cracks to form within the family.

Paul and Ally are thrilled that Sprout the family gerbil has finally died, but explaining loss to Luke and Ava is more difficult than they thought as grief manifests itself in mysterious ways and throws the family off course.

Family life is thrown off kilter as Ally spends her weekdays in Berlin and weekends in London. Paul, Luke and Ava try to muddle through without her, but the children aren’t sleeping again and it takes its toll on Paul.

Jackie’s health is continuing to worsen. Paul helps out a distressed Luke but finds himself in more conflict with Ally. At Baby Jay’s naming party, Ava declares her love, and Paul makes an offer that will take him and Ally back in time.

Ally attempts to acclimatize to Michael's continued presence while Paul begins to question if his accident-prone son's frequent injuries might actually be his fault.

In the wake of Michael’s death, the family stay with Darren at his country house, but Paul’s attempt to give Ally space by taking on kid duties and Darren’s fixation on work doesn’t help Ally find a chance to say goodbye.

The children won’t sleep – Paul and Ally thought these nights were over. Paul spends the night fighting his own anger and his children’s inability to go the f**k to sleep.

Michael thrives in his new role as dad and granddad, but Paul and Ally can't adapt to his presence as easily as the children can. Luke's hunt for proof that Santa doesn't exist puts Paul's claim that he never lies to the test.

The kids are growing up fast – Ava is now 10 and Luke is about to turn 13. With their burgeoning independence comes the question of whether Paul and Ally’s parenting style still works. Clue: no.
