The film follows both armies from the planning of Operation Torch / Operation Acrobat to the liberation of Tunis. Interspersed in the pure documentary format are the narrative voices of an American and a British soldier (voiced by Burgess Meredith and Bernard Miles respectively), recounting their experience in the campaign. The British and American talk separately until the end of the film when they have a dialogue, agree to co-operate after the end of the war, with the other Allied nations to create a more just and peaceful post-war order.
The film was intended as a follow-up to the successful 1943 British documentary film Desert Victory. Frederic Krome's article from The Historian Tunisian Victory" and Anglo-American Film Propaganda in World War II details the acrimony between the British and US film makers on the project. Most of the actual American combat footage taken during Operation Torch was destroyed when the ship carrying it was sunk, requiring many "battle scenes" to be reshot in America by director John Huston.
