Arthur C. Clarke's science fiction classic "Childhood's End" has been reimagined for the 21st century, and brought to the small screen, in a new TV miniseries debuting tonight (Dec. 14). When a fleet of spaceships appears in the sky above Earth's largest cities, the alien beings onboard insist that they have arrived to help the human race. The visitors slowly begin to eliminate war, disease and poverty -- but what will be the cost of building heaven on Earth?
