Brittas (Chris Barrie) is being hailed as national celebrity. He has founded a charity, written a book and is being backed by a national newspaper. He is looking forward to a recording of the popular TV religious series Songs of Praise at the newly rebuilt Whitbury Leisure Centre. Despite a series of accidents which leads him to believe that a serial killer may be on the loose in the Centre, Gordon is determined the show must go on. And go on it does - Colin is temporarily blinded when his garden explodes, Gavin takes over as manager for the day and, despite Brittas' absence, things do not go smoothly - it is as if a mysterious force is at work.
