Caroline gets a job at a notoriously rough school in Huddersfield and moves, with Alan and Celia and her two sons, to a ramshackle farmhouse outside the town - not that Celia is happy with her accommodation. On a girls' night out Caroline confides in Gillian, who also admits she feels haunted by late husband Eddie, especially after Robbie has a serious accident on the farm. Celia however is buoyant when she lands the role of Madame Arcati in a local production of 'Blithe Spirit' and ropes in a reluctant Alan when another cast member falls ill. Alan's friend Harry alarms everybody by claiming that Caroline's house is haunted.
