Season 4

John and Carol are in their sixties, looking forward to retirement and a quiet life. Long-suffering of each other's foibles, but always leavened with fond humour, relations are nevertheless strained by their failure to sell their house, which has been on the market for months. As they bicker about reducing the price, they are unaware that two other arguments are happening simultaneously on their street; a young couple, Sarah and Ryan, argue about money, and taxi passenger Dave complains about the fare to driver Neil. These events come to a terrible head when Ryan is fatally knocked over by Neil, outside John and Carol's house. John and Carol try to be as sensitive as they can to the mourners congregating outside their house, but as the weeks turn into months, and the shrine of flowers, cards and soft toys encroaches ever further into their lives, even John and Carol's ever-present humour starts to fade.

Liv is all things to all people: a single mum to two young boys, a housing officer for vulnerable adults, a university student and a loyal daughter to her difficult and demanding dad. She is pulled in so many directions that she has little time to think of herself, and even less opportunity to build a meaningful relationship. A chance encounter with supply teacher Aiden ignites a spark that offers Liv a real chance of the happiness and love she deserves. But Liv has a secret that threatens to ruin everything. Once a week, after dropping the boys at school, Liv dutifully travels to the prison where her father Kris is serving a lengthy sentence. These visits have dominated her life since the kids were small, and although she tries to protect them from this grim reality, they know more than she realises.

Single mum Danielle befriends Sonia, a new mother at the school.

Phil starts looking after his father following a fall, but a tragic accident ensues.

When married couple Lisa and Gary split up, they become flatmates from hell.
