Astrid

A drunken joyride turns tragic when a group of college kids accidentally run over a schoolgirl. Desperate to cover up the accident, they dismember the girl and bury her body in a remote abandoned building. Five years later, upon hearing the building is slated for demolition, they journey back to the grisly tomb to move the corpse, only to find an angry soul intent on bloody revenge.

When a comet strikes Earth and kicks up a cloud of toxic dust, hundreds of humans join the ranks of the living dead. But there's bad news for the survivors: The newly minted zombies are hell-bent on eradicating every last person from the planet. For the few human beings who remain, going head to head with the flesh-eating fiends is their only chance for long-term survival. Yet their battle will be dark and cold, with overwhelming odds.
