When six college students find themselves in desperate need of cash, they sign up for what seems to be a simple paid research study. They soon realize that this is much more than a simple study and that their lives are in danger. Unfortunately, they've unknowingly volunteered their bodies as human collateral in an ongoing covert U.S. Military experiment to test weapons of mass destruction. The experiments, led by Senator Davis and Sanders, have deadly consequences that slowly turn each volunteer into a flesh-eating zombie, forcing the students to quickly devise an escape plan.
