After a two-year hiatus Anne Reid and Derek Jacobi reprise their much-loved roles as Celia and Alan – teenage sweethearts reunited in their golden years – for a two-part special of Sally Wainwright’s hit bittersweet drama.

Set two years on from where we left them at the end of series three, the plot sees Celia landing a role in a local amateur dramatics production, and it’s not long before she gets poor Alan involved.

Meanwhile, Celia’s daughter Caroline (Sarah Lancashire) and Alan’s daughter Gillian (Nicola Walker) are, as usual, causing problems all round.

Superbly written and beautifully acted – don’t miss! Concludes tomorrow night.
