(USA TODAY) -- Beware the winds of vengeance.

That's the big message that comes through the newly released trailer for 300: Rise of an Empire.

The first extended look at the highly anticipated follow-up to 300 features the beautiful but dangerous Artemisia (Eva Green), the general of the Persian navy.

"She'sseeking revenge and she does it well," says Sullivan Stapleton, whoplays the Greek leader Themistocles. He would know. His outnumbered navyfaces Artemisia's wrath in the new film.

Artemisia's beef withthe Greeks? Well, when she was a child they killed her family, an actwhich is alluded to briefly in the trailer. In the movie, she's grownup, beautiful and gunning for revenge.

"She's got sex appeal,"says director Noam Murro. "She is ruthless and cunning. All the thingsthat kill men. And she has a sword."

Not to mention a massive Persian navy.

300: Rise of an Empire is not a sequel to the 2006 box office hit 300.The movie takes place at the same time, but at sea in primarily smallboats. Themistocles must rally his rag-tag navy to fight off the massiveonslaught.

"It is tied visually to the original," says Murro. "But there is a whole different choreography of fighting and war."

"Thefew against the many is still here," Murro adds. "It's hundreds versushundreds of thousands. It's about taking on the mightiest power of allwith wisdom and tactics."

300: Rise of an Empire hits theaters March 7, 2014.
