The police in Ashfordly have been asked to look out for Stevie Walsh who has been released from prison after serving a ten year sentence for armed robbery. His wife Ellen still lives in Aidensfield and it is believed he will go there to collect the money from the robbery which has never been recovered. But a severe snow storm is brewing and in the bad weather the train carrying Walsh, Gina's cousin Barry and Dr. Ferrenby crashes near the station in Aidensfield, and everybody has to lend a hand in the emergency. To complicate matters Ellen Walsh is pregnant with her new boyfriend and Kate Rowan is out in storm trying to deliver the baby, and she knows nothing about the train crash.
