Christmas 1962 sees an unprecedently heavy snow fall and a burst pipe in the community hall requires the clinic to be held in a local pub as well as cancelling the pantomime. Valerie trawls through the drifts to the caravan where pregnant Linda is staying with the adoring Selwyn, who knows he is not her baby's father, for a potentially upsetting early birth whilst Sister Julienne hears a shocking story of domestic abuse when she visits the wife of a hypothermia victim. Come the New Year the pantomime goes ahead and Phyllis gets the better of an officious policeman but Tom is faced with a difficult decision.
