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.

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.

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.

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.

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.

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 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.

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.

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.

Ally fears she might lose her job and her mind as the company collapses and her HRT medications become unavailable. Luke’s panic attack ends Paul’s leisurely life at Leah’s. An increasingly isolated Ava faces a huge change.

A back injury leaves Paul high on Leah's supply, as he raids her collection of heavy-duty painkillers. As Luke and his dad get closer, Ally and Ava drift further apart, and Ally looks for someone to blame.

Ally and Paul each learns the truth about a thing that has been terrifying them - for Ally, her job and for Paul, his MRI result. Ava and Luke both feel frozen out by the people they care most about.

An ambitious Ally sets out to save the company and throw a memorable birthday party for Ava, just as Paul, passed over for promotion yet again, wonders if he ever had any ambition to start with.

Jim and Jackie are both struggling under their new circumstances. Luke has to choose between Jacob and Ruby. At Alex's 65th birthday party, Ally meets someone who makes her see Paul in a new light.

A furious argument between Paul and Ally is interrupted by Ava's news about Jim. Luke is happier than ever, a newly confident Ava stands up to her dad, but Paul and Ally need to decide - is this it?

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.
