I. 'NEWS FROM ENGLAND.' An introduction to some of the latest types of United States aircraft arriving disassembled in crates as part of the Anglo-American lend-lease scheme. Crated aircraft parts are towed into an assembly area. Anti-corrosion paint is scraped off the fuselage of a Douglas Boston bomber. A propeller is mounted on a Boston engine nacelle (1,600-hp Wright R-2600 engines ?) using a winch. Assembly workers attach bomb racks in an aircraft's bomb bay as a woman assembly worker cleans the plexiglass nose of the aircraft. The commentary asserts that aircraft such as these are shooting down Nazi aircraft over Libya and the Russian front. Various other lend-lease aircraft are displayed including a Pitcairn autogiro (military version of PA-34 autogiro) in RAF markings, Martin Baltimore bomber, Fairchild 41 liaison aircraft, Curtiss Mohawk fighter and Boeing B17C Flying Fortress bombers. The commentary outlines the many and varied jobs carried out by RAF groundcrew maintenance and supply units. Women's Auxiliary Air Force members (WAAF) operate Singer sewing machines tailoring uniforms and making Union Jack flags. Aircraft fabric is sown prior to cellulose doping and fixing to airframes. RAF mechanics listen attentively to a lecture given on the workings of the internal combustion engine. RAF groundcrew winch 250lb bombs into an aircraft's bomb bay. RAF emergency fire crews wearing fireproof asbestos overalls walk through flames during a practice session, as the commentary stresses that this dangerous job is reserved solely for men. WAAF members gain familiarity with aircraft reconnaissance cameras and photographic development techniques. Elsewhere, bomb making processes are highlighted at a munitions factory. The commentary outlines the production stages involved in bomb manufacture from the melting and moulding of metals to the painting of the finished article. A bomb casing is removed from a furnace by a male factory worker and dropped into a special cooling chamber. Hydraulic presses form bomb casings which are then taken to another point in the production line for machining. Women factory workers finish the production process by polishing the bomb casing prior to painting. The bombs are stacked in a storage area pending delivery to RAF Maintenance Command.

II. 'SOUTH AMERICA.' The commentary stresses that the United States' policy of "good neighbourliness" has borne fruit with Brazil becoming actively sympathetic to the Allied cause. Three Italian built Tamoio Class submarines of the Brazilian Navy are moored at an undisclosed location. The commentary states that Brazil has recently modernised her submarine fleet. Various views of the Tamoio Class submarines in close formation surface manoeuvres, followed by a brief internal view of a submarine's bridge and map room.

III. 'CANADA.' The commentary introduces the work of a Montreal tank factory and states that the Valentine tanks being produced are destined for locations such as Russia, Britain, the Middle East and the Far East. Scores of Valentine Mk VI tanks are parked in a production depot awaiting the installation of their main armament. More Valentines are manoeuvred into position in the storage area. The commentary states that each tank completed ahead of schedule is another nail in Hitler's coffin. A supply train carrying Valentine tanks bears the legend "Valentines for Victory".

IV. 'NEW ZEALAND.' New Zealand's contribution to war effort. A map of the Japanese Islands shows by means of strategic arrows, Japanese expansionist ambitions in the region. The commentary points out that Australia and New Zealand, although previously far from hostilities, now find themselves in the front line. New Zealand Infantry march past cheering civilians followed by members of the New Zealand Army Nursing Service and Women's Army Auxiliary Corps. Elsewhere, New Zealand's raw material and food production is being placed on a war footing. Flax is harvested by a farmer, useful in the production of aircraft fabric. A dairy worker moulds cheese by hand as the commentary highlights New Zealand's role in supplying Britain with essential foodstuffs. Textile mills produce material for uniforms which is tailored by women workers and then pressed using steam machines. The work of New Zealand's war production and munitions factories are highlighted including an assembly line producing suspensions for Bren gun carriers and Mills 36M grenade cast iron casings being machined. A completed Bren gun carrier is driven from a factory resplendent in new camouflage paint. Cavalry units practice manoeuvres as infantry in gas masks emerge from a smokescreen armed with Thompson M1928 .45-inch sub-machine guns (box magazine). New Zealand Valentine tanks on exercise. An infantry detachment mount a Vickers .303 inch Mk 1 heavy machine gun on its tripod. The commentary stresses the thoroughness of New Zealand's military training programme, the quality of which was demonstrated in Greece, Libya and Crete. A Universal Carrier moves at speed past the camera as New Zealand infantry march past a reviewing podium. The commentary points out that military ship building is a major development since the war over scenes of a ship without its superstructure sliding down a slipway into water (ship may possibly be either Kiwi or Tui type armed trawler). The commentary highlights the reputation that the New Zealanders have for flying and outlines the training processes of a Royal New Zealand Air Force (RNZAF) pilot. Flight trainees are given a lesson in basic aerodynamics and the effect of aircraft controls using an instruction model. Aircrew pose for the camera in a "group shot". RNZAF Airspeed Oxford training aircraft overfly a snow capped mountain range. The role of the Territorials in coastal defence is outlined over scenes of coastal guns firing from substantial concrete defensive emplacements.
