Summary: The monoliths have been watching us. They gave us the "evolutionary kick in the pants" we needed to survive at the Dawn of Time. In 1999, we discovered a second monolith on the moon.. Now, in the year 2001, the S.S. Discovery and its crew, Captains Dave Bowman and Frank Poole, and their onboard computer, HAL-9000, must discover what alien force is watching us...
