Some activities only occur when the world is dark. We stay up late off the coast of California to hunt some slippery and slimy nocturnal creatures: squid by the tens of thousands. Fishermen show us how they lure them into their net by mesmerizing them with the boat's powerful lights. We also visit Toronto, Canada, the self proclaimed "worm capitol of the world", where an army of pickers pluck countless night crawlers emerging from their burrows. In Tennessee, we put a night vision lens on our camera to capture the action as military trainees try their hand at the latest night vision gear. And we'll experience how hard it is to evade a police helicopter's blindingly bright Spectrolab spotlight, or powerful noses and sharp teeth when the cops deploy their K-9 units. For some after hours fun, we'll see how more than six hundred, 2,000 watt lights can turn night into day inside the Pittsburgh Pirates' new state-of-the-art stadium.
