The Randalls were married in Aidensfield and they want their daughter to be wed at the same church. But Rev. Truscott is in dire need of bell ringers and asks Dr. Alway to help him out. The doctor enlists David and the Scripps's as his helpers, but bell ringing takes time to learn and not everybody in the village are that keen on the ringing of bells in and out of season. Lord Ashfordly is not satisfied with the income from his quarry. Therefore he hires Oscar Blaketon to keep an eye on the manager Mr. Briggs. Following an anonymous call the police discover that explosives are missing from the quarry. They also have to deal with the security in connection with the defence minister's visit to Fylingdales radar station. Oscar Blaketon has problems of his own. He has returned from a holiday in Spain with an accusation of violence hanging over his head.
