Civilization is gone, buried in the rubble and bodies of a thousand cities. The mindless zombie hordes number in the millions, roaming the earth, hunting, killing, looking for the last few survivors. Off the coast of California, a group of survivors desperately clings to life in a small flotilla, which is slowly getting smaller as they are beset from the inside as well as out. Another squadron of ships seeks to rendezvous with them, but they are being hunted by a wolf pack of Russian submarines, and it is unlikely they will make it in time. There are other groups trying to live as well. While most are trying to help each other, one is going in its own direction. They were prepared for the alien Strain Delta and have been working toward a secret goal all along. Time is running out for humanity as the clock slowly ticks down to midnight. If we are to have any chance of surviving, we must decide if it is a time to live.
