In Season 2, the six-part series returns as Alan and Celia continue to negotiate family baggage to plan a life together.
Having come so close to losing each other forever thanks to Alan's near fatal heart attack, he and Celia decide to have a romantic secret wedding as soon as possible. But how will their respective daughters react?
The uptight Caroline and rebellious Gillian are discovering they actually quite like each other, however Gillian's need to own up to her night with Caroline's ex-husband John could jeopardize the soon-to-be stepsisters' fledgling friendship.
As secrets from the past come tumbling out and family members adjust to changing relationships, can Alan and Celia find the long-awaited happiness they deserve?
In the first episode of Season 2, we pick up from where we left off with Alan (Derek Jacobi) regaining consciousness from his heart scare, much to Celia's (Anne Reid) relief and delight. She promises to never fall out with him again and reflecting that life's too short, they decide to get married... in just a fortnight's time!
Things between Caroline (Sarah Lancashire) and John (Tony Gardner) become fractious when Caroline returns home to find John and Judith (Ronni Ancona) drunk and in her bed.
To retaliate, she invites Kate (Nina Sosyana) to move in. She won't be made a gooseberry in her own home. And finding out that he slept with Gillian adds to her distain.
Gillian (Nicola Walker) and Alan's relationship takes a hit when he finds out she's slept with John. It's one disappointment after another. In the heat of the moment he reveals to Celia that Gillian had an abortion when she was 15.
Two weeks later, Gillian finds the registry card with a reminder of the wedding date and it's today! Why hasn't she been invited? Gillian grabs her keys, but can she get there in time?
