East South West North strings together the tale of what happens when China's infamous "human search engine" gets it wrong. A university student brags about being a "kept mistress", the human search engine goes to work and posts photos of a girl living in Chengdu alleged to be her - the girl's blog is blasted, her private information passed out, her phone rings non-stop, her computer is under attack - but she's not the mistress - they got it wrong - and now she's suing.
