As the Persians, led by the cunning General Artabanus, approach Sparta, the young Leonidas prepares for battle. With the help of a few surviving Spartans from his father's time and some new, skilled recruits, they devise a plan to defend their homeland.

Both 300 and its sequel are highly fictionalized. Historians note:

"300" is a historical action film directed by Zack Snyder, based on the 1998 comic book series of the same name by Frank Miller and Lynn Varley. The film depicts the Battle of Thermopylae, where a small contingent of Spartan warriors, led by King Leonidas, fought against the invading Persian army.

However, in 2021, Warner Bros. announced that a 300 prequel TV series was in early development for HBO Max. The series would reportedly explore the origins of the Spartans and the politics of ancient Greece. While not a movie titled 300 3 , it is the closest thing to a continuation of the franchise.

Unlike a traditional sequel, this film takes place the events of the first 300 movie. While King Leonidas and his 300 Spartans fight on land at Thermopylae, this story focuses on the massive naval battles occurring simultaneously.

The movie takes place during the same time period as the original, but with a different storyline. The plot follows the story of Themistocles (Sullivan Stapleton), an Athenian general who teams up with the Spartans to defeat the Persian Empire and its ruthless leader, Xerxes (Rodrigo Santoro).
