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.

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.

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.

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.
