The film is a spoof of the 2006 action movie 300 . It follows King Leonidas (Sean Maguire) as he leads a small group of Spartans (13, rather than 300) to defend the Hot Gates against the invading Persians. However, instead of a serious battle, the movie relies heavily on pop-culture references, slapstick humor, and celebrity cameos (including parodies of Britney Spears, Paris Hilton, and Spider-Man). It is known for its "breaks the fourth wall" style and absurdity.

The film was critically panned, holding a very low rating on aggregator sites (generally around 2-3/10), but it developed a cult following among fans of the specific parody style popular in the mid-2000s.
