"A new realm is not built in a day — it is burned into being."
The story opens on the isle of Dragonstone, where Aegon Targaryen — Lord of the island fortress and last scion of old Valyrian blood in the west — gazes upon the crudely drawn map he has painted of the Seven Kingdoms. For years he has dreamed of uniting what no man has ever unified. With his two sister-wives, Visenya and Rhaenys, and their three dragons, he lands on the mainland with a modest host and proclaims himself King of All Westeros. One by one the petty kingdoms react: some kneel, some defy. The Gardener kings of the Reach and the Lannister lords of the Rock forge an alliance and march a great army of half a million men to crush the upstart. At the Field of Fire, Aegon and both his sisters ride their dragons simultaneously for the first and last time in the war, unleashing a cataclysm of dragonfire. The Gardener dynasty is extinguished, the Lannisters submit. In the east, Visenya flies alone on Vhagar to the Eyrie, where a child-king and his regent mother yield without a drop of blood. The film closes with the raising of the Targaryen banner over newly-named King's Landing and Aegon's coronation beneath the open sky.
