A disaster strikes without warning. People panic, overwhelmed by fear of the unknown as darkness closes in. In this moment, the ugliness and beauty of human nature are laid bare. Someone who begged you for a sip of water just moments ago might attack you the next moment for a bottle. And the fierce-looking brute you see may turn out to be a rare, selfless saint. Whatever your status, whether a business tycoon or a political heavyweight, your former arrogance is gone. The glamorous star of yesterday is now no better off than a beggar. Your past is nothing more than a label for reference. Now, all you can rely on is your wits and strength. Only by staying alive can you uncover the truth behind it all.
