Prowl (2010)

Amber decides to move to the big city as she sick of living in a small town.  She and a group of friends decides to treat this as a road trip but their car breaks down.

They flag down a trucker and convince to give them a ride.  Bad move, kids. Don't you know you should never accept rides from strangers, even if you procure them?

There's only room for one up front, so the rest get in the back of his truck, and by truck I mean big rig.  In other words, they are locked inside the back of an 18 wheeler.  Oh no, this won't do.

They spend their time partying, but eventually realize that they are heading the wrong way. They frantically try to get the trucker to stop.  He won't.  Panicked, they start looking through the cargo and find it's blood.

Eventually the truck stops at an abandoned warehouse in the middle of nowhere.  The back door is unlocked and the group step out into the warehouse to find creatures right out of 30 Days of Night.  Will they survive? Will they escape?  Will you care?
