When a meteor shower rains down outside Los Angeles, Lars and Jonas, two friends stuck in tired, boring lives, head out to find one and strike it rich. After recovering one, they start being stalked by Terrordactyls, ancient flying reptiles, that launch a full-on assault on the city. They go on the run, trying to survive, where the unlikely heroes, along with Candice, a tough-and-sexy bartender, Valerie, her sultry roommate, and Sampson, a constantly drunk and sassy ex-marine, soon discover that there's more to the meteor than meets the eye. They must learn to put their differences aside, and fight back to make the Terrordactyls extinct once again.

Desperate to cure her near catatonic sister, intrepid authoress Adèle Blanc-Sec braves ancient Egyptian tombs and modern Egyptian lowlife to locate a mummified doctor and get him back to Paris. Her hope is that oddball Professor Espérandieu will then use his unusual powers to bring the doctor back to life so he, in turn, can use his centuries-old skills on the unfortunate sister. In Paris however Espérandieu is already causing mayhem, having brought to life what was a safe museum egg but is now a very active pterodactyl. Paris 1911 may not be the healthiest place to be.
