"Nova" takes you on a high-voltage trip into the most electrically charged weather in the world, culminating in a dazzling lightning show set to music. Join scientists as they tempt nature by creating the world's tallest lightning rod, which triggers awe-inspiring thunderbolts a few hundred feet from observers and creates a chunk of "petrified" lightning. Then, visit with some of lightning's tragic victims who thought they were out of harm's way.
