Barbra and Johnny visit their father's grave in a remote cemetery when they are suddenly set upon by zombies. Barbra manages to get away and takes refuge in what seems to be an abandoned farm house. She is soon joined by Ben who stopped at the house in need of gas. Beset by the walking dead all around them Ben does his best to secure the doors and windows. The news reports are grim however with creatures returning to life everywhere. Barbra and Ben are surprised when they realize there are 5 people hiding out in the basement: Harry, Helen and Karen Cooper; and a young couple, Tom and Judy. Dissensions sets in almost immediately with Harry Cooper wanting to be in charge. As their situation deteriorates, their chances of surviving the night lessen minute by minute.

"2001" is a story of evolution. Sometime in the distant past, someone or something nudged evolution by placing a monolith on Earth (presumably elsewhere throughout the universe as well). Evolution then enabled humankind to reach the moon's surface, where yet another monolith is found, one that signals the monolith placers that humankind has evolved that far. Now a race begins between computers (HAL) and human (Bowman) to reach the monolith placers. The winner will achieve the next step in evolution, whatever that may be.
