 One morning, George Mainwaring, the manager of the Walmington-on-Sea branch of Martins Bank, and his chief clerk, Arthur Wilson, listen to Anthony Eden making a radio broadcast about forming the Local Defence Volunteers (LDV).At the local police station chaos ensues because there is nobody to organise the enrolment of the men.Characteristically, Mainwaring takes charge and after commandeering the local church hall he registers the assembled volunteers.
