In three months in 1940, 26,000 men joined the Ulster Home Guard. The Fire Service tripled in strength, and there were 13,000 Air Raid Wardens and 19,000 members of the Womens’ Voluntary Service. Made with the full co-operation of the RUC, The Story of The Ulster Home Guard somewhat ignores the organisation's controversial history, preferring to offer a straightforward celebration of the force's activities. The film was shot after the stand down of the Guard and therefore consists primarily of reconstructions. The film seeks to stress the Guard's shared participation in the British war effort.
