A gunslinger is embroiled in a war with a local drug runner.

The residents of a rural mining town discover that an unfortunate chemical spill has caused hundreds of little spiders to mutate overnight to the size of SUVs. It’s then up to mining engineer Chris McCormack and Sheriff Sam Parker to mobilize an eclectic group of townspeople, including the Sheriff’s young son, Mike, her daughter, Ashley, and paranoid radio announcer Harlan, into battle against the bloodthirsty eight-legged beasts.

Sam Montgomery is a tomboyish, unpopular girl at school. She has been text messaging a somebody named Nomad for a few months and he asks her to meet him at the Halloween dance at 11:00 in the middle of the dance floor. The only problem is, she must get back to the diner, ran by her wicked Stepmom Fiona by 12 sharp because she is not supposed to be there. Before Nomad can found out who she is, she must leave with her best friend, Carter driving her back to the diner. After that night, everything in Sam’s life goes wacko!
