Four reels only of the Italian feature based on the defence by Franco supporters of the Alcazar fortress in Toledo against besieging Republican forces in the Spanish Civil War.
The four reels held show: 2. News reaches Toledo of Franco's mutiny; as workers demonstrate in the street, the garrison opts for Franco; the Minister of War issues an ultimatum; women and children shelter in the Fortress cellars. 3. The attack starts: aerial bombing and an undisciplined charge. Hard-pressed outposts hold out (one steals the Republican cry 'No Pasaran'). Preparations are made for siege in the fortress itself (boys trained in rifle use). 7. A priest is admitted to the garrison, celebrates Mass, administers Last Rites and performs a death-bed marriage. 9. A determined Republican assault; grave supply situation; an officer prepares in disguise to penetrate the besiegers' lines.
