The 300 Spartans

Plot

King Xerxes I of Persia leads a vast army of soldiers into Europe to defeat the small city-states of Greece, not only to fulfill the idea of “one world ruled by one master”, but also to avenge the defeat of his father Darius I at the Battle of Marathon ten years before. Accompanying him are Artemisia, the Queen of Halicarnassus, who beguiles Xerxes with her charm, and Demaratus, an exiled king of Sparta, whose warnings Xerxes does not heed. Xerxes releases a captured Spartan soldier, Agathon, and tells him to inform the Greeks of their impending doom.

The 300 Spartans

In Corinth, General Themistocles of Athens wins the support of the Greek city-states and convinces both their delegates and the Spartan representative, King Leonidas I, to grant Sparta leadership of the allied Greek forces, with Themistocles himself put in charge of the Athenian navy, recently reinforced with two hundred new ships. Outside the hall, Leonidas and Themistocles agree to fortify the narrow pass at Thermopylae with a vanguard force until the rest of the army arrives.

The 300 Spartans

After learning of the Persian advance from Agathon, Leonidas travels to Sparta to rally the troops. In Sparta, his fellow king Leotychidas II is fighting a losing battle with the ephors – a council of five magistrates – over the religious harvest festival of Carneia that is due to take place, with members of the council arguing that the army should wait until the festival is over before marching to war, while Leotychidas fears that by that time the Persians may have conquered Greece. Leonidas decides to march north immediately with his personal bodyguard of 300 veteran men, who are exempt from the decisions of the ephors and the Gerousia, while Leotychidas remains in Sparta. The 300 Spartans are subsequently reinforced by a contingent of about 700 volunteer Thespians led by Demophilus, and a few other Greek allies.

After several days of fighting, Xerxes grows angry as his army is repeatedly routed by the Greeks, with the Spartans in the forefront. Leonidas receives word sent by his wife that, by decision of the Ephors, the remainder of the Spartan army, rather than joining him as he had expected, will only fortify the isthmus in the Peloponnese and will advance no further. The Greeks constantly beat back the Persians; following the defeat of most of his "Immortals" (personal bodyguard) by the Spartans and the death in battle of two of his brothers, Xerxes begins to consider withdrawing to Sardis until he can equip a larger force at a later date.

He prepares to withdraw, as advised by Artemesia (who, having a Greek mother, may have her own agenda to dissuade the king from continuing the invasion). Xerxes, however, receives word from the treacherous and avaricious Ephialtes, who has been also spurned by Spartan maiden Ellas (who accompanied her Spartan soldier boyfriend Phyllon to the battlefield, where he wishes to prove his courage), of a secret old goat-track through the mountains that will enable Persian forces to attack the Greeks from the rear. Promising to richly reward the traitorous goatherd for his betrayal (as Ephialtes had expected), an emboldened Xerxes sends his army onward. The Phocian troops dispatched by Leonidas to guard the secret path are summarily defeated.

Once Leonidas realizes he will be surrounded, he sends away the Greek allies to alert the cities to the south. Being too few to hold the pass, the Spartans instead attack the Persian front, where Xerxes is nearby. Leonidas is killed in the melée. Meanwhile, the Thespians, who had refused to leave, are overwhelmed (offscreen) while defending the rear. Surrounded, the surviving Spartans refuse Xerxes's demand to give up Leonidas' body in exchange for safe passage. They are then all annihilated as the remaining Immortals rain down a barrage of arrows.

After this, narration states that the Battle of Salamis and the Battle of Plataea end the Persian invasion, but that the Greeks could not have been organized and victorious without the time bought by the 300 Spartans who defied the tyranny of Xerxes at Thermopylae. One of the final images of the film is the stone memorial bearing the epigram of Simonides of Ceos, which the narrator recites in honor of the slain 300 Spartan men's bravery :
