Set during the London Blitz of 1940, Tommy Trinder stars as a kennelman who volunteers for the East End Auxiliary Fire Service. The volunteers have to work alongside the regular firemen, who resent the amateurs but who could also not have saved so many lives without them. This film was made in 1943 with the help of the National Fire Service and is now seen as a tribute to all the professionals and volunteers who put their lives at risk saving others.
