It depicts a small group of people in a Reno, Nevada casino who have survived a nuclear disaster while the rest of humanity has been turned into flesh eating zombies.

Tom (Grant Bowler) and Tori (Evalena Marie) are employees at the fictional Silver Star Casino in Reno.

On a slow day at the tables, Tom convinces Tori to join him in a stock room for a sexual encounter.

Something goes wrong during the event and a nuclear blast occurs, knocking out power to the casino and trapping Tom and Tori behind an electronic lock.

Jensen lets him in and takes him to a bathroom to clean up while Tom and Tori decide to start trapping the other zombies in the casino.

Deciding to use a spotlight from across the street to attract the convoy, they head out at night past the sleeping zombies.

The army's medic, Cindy (Tawny Cypress), patches up Tom's hand and tells them that the group is headed to Lake Tahoe.

The soldiers force Tom to show them where it is, and he opens the door to release dozens of zombies that he and Tori trapped in the room earlier.

In the final scene, a zombified Tori carries her shotgun and kills the weaker zombies—implying that she is stronger, faster, and still retains her human intelligence—and looks toward the direction where Tom and Cindy drove.
