Savage dinosaurs are caught in a time wave and descend upon the historic city of New Orleans, Louisiana. The Big Easy's jazz scene, culinary escapades, and party-time debauchery plunge into chaos as revelers drop their bloody Mary's and daiquiris for a brutal fight to the death. On the Mississippi River, a giant squid and elasmosaur pick tourists off the paddlewheeler Southern Queen. Pterodactyls terrorize the skies above Louis Armstrong New Orleans International Airport. A giganotosaurus tramples beautiful Jackson Square. Troodons and dilophosauruses invade the Audubon zoo. A brontosaurus runs wild on Bourbon Street. No one is safe as strangers forge alliances to battle the onslaught of prehistoric beasts raging havoc with sharp claws and spiked teeth threatening human flesh.
