Plot.
When a top secret Black Ops facility is breached from within by genetically modified Monolophosaurus, a final shipment is re-routed to a nearby prison to secure a half dozen of the beasts. 
A trio of sorority girls (who are temporary 'guests' after getting busted for high-jinx after a particularly obnoxious party) find themselves trapped in the prison when these dinosaurs escape and go on a vicious rampage killing 90% of the prison population including the guards. 
Forced to team up with the remaining prisoners they find themselves pushed deeper and deeper into the bowels of the prison to find a way out. Only they aren't sure if their new 'friends' are any better than the Monolophosaurus who plan on eating them.
And to make matters worse the Black Ops organization enters the prison not only to collect their 'property', but also permanently silence anyone with knowledge of the situation.
