Paul takes his parents on a day-trip to the countryside, to recreate a cherished memory. But the revelation of a number of secrets leaves all three of them reeling.

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.

As Jim and Jackie's golden wedding anniversary party is plunged into darkness by a power outage, the growing tensions between Paul and Luke reach an explosive and terrifying climax.

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.

A sudden death impacts the older generation of the Worsley family. Ava struggles to keep a profound secret from Paul. Ally finds it difficult to hide her true feelings from Luke.

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.

On the day of Leah and Alex's wedding, Paul and Ally find they have only a few hours to deal with a family crisis, leading Paul to make the hardest decision of his life.

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.

Paul fears his culturally fragmented family has lost a vital connection. Gentrification impacts Jim and Jackie as the last of their old neighbours move out and more young professionals move in.

As he and Ally continue to feel distant, Paul rekindles an old friendship, but at a cost to Ava. Luke surprises everyone by getting a best friend. Jim and Jackie are forced to move.

Luke’s anxiety is becoming a problem at home and school. Would a medical diagnosis make his life easier or harder? Ally faces further tension after her mother Leah is robbed.

As Ally contemplates her pregnancy, a new piece of information blows her world apart. A worried Ava tries to help her mum while Luke regrets lying.

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 is under huge pressure, but no one seems to want to listen to her; Jim and Jackie are excited about a possible move to the coast and, much to Paul's surprise, so is he.

Ally and Paul's marriage is in crisis. Paul's obsessed by what happened but won't discuss it. An increasingly troubled Luke refuses to go to school and Leah and Alex make an announcement.

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.

It’s half term and Luke is responsible for taking Lenny the class bear on an adventure. Lenny has been to Italy, Peru and beyond, but Paul can’t even manage to get the family and the godforsaken bear out of the house to the local park.

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.

Paul attempts to focus on his upcoming wedding but is constantly thwarted by his family; Ally is distracted by work, Luke is misbehaving at school and Leah (Stella Gonet) doesn’t understand why they are even bothering to get married.
