In pre-war Britain, newsreel Chief Will Ferguson (Will Fyffe) and his son Steve (Anthony Hulme) plan to make a documentary celebrating human achievement - but the events in Europe sour their plans. Hitler's Third Reich is on the march and has just invaded Czechoslovakia. Europe is in flames and instead they make a documentary fiercely condemning the rise of Fascism. Steve leaves for South America - but as World War Two erupts in all its fury he soon finds that the war has followed him. The Giant German battleship Graf Spee has fled into Montevideo Harbour after a punishing encounter with the British warships Exeter and Ajax. As events unfold in a very unexpected way, Steve is there with his newsreel camera to capture the dramatic end to the encounter. Made in 1940 and starring Will Fyffe, this stirringly patriotic film boosted morale in the nation's cinemas, cleverly combining new scenes with genuine newsreel footage to show one of Britain's great naval triumphs in the early months of the war.
