The day of Nick's and Jo's wedding has arrived. To calm his nerves Nick takes a ride in his car when he is flagged down by a woman because of an accident. Suddenly the woman drives away in his car and Nick is stuck miles away from everywhere on the moors with an injured man on his hands. He manages to get the man to hospital, but time is getting short if he has to make it to the church in time. Sergeant Blaketon's day of retirement is nearing and he has applied for a year's extension of service, but the news from his medical exam is not good. News is not all bad though because they will also get a new police constable in Ashfordly.
