Last Tango In Halifax: Season Four

Catch up with the lives and relationships of reunited childhood sweethearts Alan (Derek Jacobi, Vicious, The Kings Speech) and Celia (Anne Reid, Upstairs Downstairs, Bleak House) and their family members in this warm and witty two-part special. To Celia's dismay, Caroline (Sarah Lancashire, Happy Valley, The Paradise) takes on a challenging new headship role at a troubled state school and buys a rundown farmhouse nearby. Is there more to this big upheaval than she's letting on -- and will her move prompt her mother and Alan to finally find a place of their own? Meanwhile Gillian (Nicola Walker, River, MI-5) is struggling to adjust to new husband Robbie being around all day since he retired from the police. With Celia trying to rope a reluctant Alan into her new amateur dramatics hobby, Caroline negotiating a tricky new relationship and Gillian fighting a compulsion to confess to Robbie how his brother really died, life for these much-loved characters is as complicated as ever.
