Seven years into their marriage, Alan and Celia aren’t seeing eye to eye. Tempers get frayed at Caroline and Gillian’s joint birthday celebration when Celia can’t hold her tongue.

Celia is quick to apologize for causing a scene, but with Alan seeking excitement outside the bungalow, and Celia seeking it within, their relationship comes under increasing strain.

Alan's new supermarket job brings an unexpected challenge in the form of Harrison, and an overburdened Celia is called upon to travel by bus.

Ted and Harrison go on an adventure; Gillian is pushed to the breaking point at the farm; Caroline finds herself at the heart of an unlikely love triangle.
