The movie starts by showing soon to be King Leonidas as a boy preparing to be a warrior. He starts by having to survive an wolf attack. It then fast forwards to when Leonidas became king.
A Persian messenger then comes to Sparta and says that if the Spartans give Earth and water to Xeroxes then there will be no war. King Leonidas then states one of the most famous lines. He yells “This is Sparta” while kicking the messenger down and pit. King Leonidas then visits the oracle and mythological characters so he can gain their favor.
The oracle states that they should not go for it would be in the middle of a religious festival. Leonidas defies the oracles and takes 300 of his best men to the hot gates while saying he is just going on a stroll. Before he leaves he says goodbye to his wide and she hands him her necklace. While on the way to the “Hot Gates” they run into some allies who are shocked by the small number they have. When they arrive at Thermopylae the construct a wall to try and stop the Persians advance. After they do that a strong storm destroys some of Xerces’ navy, however it is just a small number compared to what they have to face later. The next thing that happens is that while Leonidas is on a hill he meets a horribly disfigured man who warns him of a path. He then asks the man how far he can raise his shield enough to defend the men he is fighting with.
The man cannot raise his shield as high as needed to protect his men; Leonidas gently tells him to choose something else. The man’s dreams are crushed and he becomes a traitor. A Persian messenger then arrives and they find a wall built with corpses. The messenger then states that the Persian arrows will block the sun. The Spartan states then states that they will fight in the shade. Next, the Persians want the Spartans to surrender but they do not.
Using their phalanx formation they Spartans move the Persians into a narrow cavern, which then causes many causalities due to their numbers. Xeroxes then approaches Leonidas and says that he should surrender. This is the time when a very famous line is said. The line stated is ” “The World will know that free man stood against that stood against the tyrant and few stood against many and before this battle was over that even a god king can bleed”. Xeroxes annoyed at Leonidas answers send out “The immortals”.
They Spartans make sure the world knows that they are not immortal. The battles continue with the animals from Persia. Many of these animals are mythological.
At the end of the battle some Spartans are killed. It becomes evident many more will be killed. Next, the disfigured man steps up to Xeroxes and tells him that he will tell him about the goat path in exchange for many things. Xeroxes agrees as long as he bows down to him. The movie then goes back to Sparta, where Queen Gorgo wants to convince the council to send men to help her husband.
The men who get her a meeting with them then states that she will have to get Theron on her side. Once the Spartans reach the Hot Gates once again they realize that they have been betrayed. The Arcadians, the allies, retreat because they know they will die. Leonidas then send a messenger, Dilios, to go back to Sparta and tell of their death. Leonidas then hands the messenger the necklace Gorga gave to him before he left.
Back in Sparta, the queen tell her request to the council. Theron, who was supposed to support her betrays her and tells the council that she has been committing adultery. Gorgo then stabs Theron and when she does a bag filled with Persia coins fall out and the council realizes that he was a traitor. Once again, at the Hot Gates the Spartans have created a dome using their shields, while Leonidas stands in front of it.
One of the Persians generals says they should surrender; the disfigured man also states that as well. King Leonidas the says to the disfigured man “May you live forever” which was an insult to him. Leonidas then drops his shield and his helmet making it seem like he will surrender however one of the soldiers jumps out of the dome leaps over Leonidas and kills the general.
Leonidas then throws his sword at Xerxes cutting open his check. By doing this he is completing the action of “making a god king bleed.” After this much of the Spartans army is killed. Leonidas final moments are spent by saying out loud that he loves his wife.
Then arrows blot out the Sun and Leonidas is killed. Thistale is told before tells this tale before an group of Spartans before they areabout to go to battle. Praising this sacrifice of King Leonidas leads the Greekarmy in to the Battle of Plata.
