A pandemic virus has already spread worldwide, killing almost everyone. Two brothers, Brian and Danny, along with Brian's girlfriend Bobby and Danny's friend Kate, are heading to a place called Turtle Beach where they believe they can wait for the viral pandemic to die out. On their way there, they meet a man and his infected young daughter and end up taking them to a place where a serum for the pandemic has been developed. They discover that that the serum doesn't work, and Bobby is accidentally infected by the little girl, though she hides this from the others. They leave the man and his daughter behind. Later, though Bobby tries to prevent it, Brian kisses her. Bobby's infection is discovered shortly thereafter, Kate stresses that they will end up dead if Bobby continues to travel with them and they end up leaving a weeping Bobby behind at a deserted gas station.
