In Guesta Verde University, the deranged Professor Curien is trying to bring back the dead, killing students for the experiment. There is an outbreak of zombies in the campus, and the government sends a NSA medical research team, formed by Dr. Alexandra Morgan a.k.a. Nightingale and lieutenant Ellis, with a special force leaded by lieutenant Dalton, trying to get the zero sample from the first generation zombie. The team has a very short time to accomplish their mission and leave the place before missiles are sent to destroy the area. However, the place is crowded of hyper sapiens and the group has to fight to survive.
A group of scientists are experimenting with time travel, and they manage to send one of their group ahead in time one hour. But when he comes back, he tells them that they’ll all be dead within the next hour unless they shut the machine down.
