Anything to get into Harvard

A Chinese couple, Gerald and Lily Chow, apparently thought that nirvana was their sons being admitted to Harvard.  They were willing to hire a consultant, Mark Zimny, to make that happen.  They paid him $2,200,000 to achieve their nirvana. Now, they are suing him for lying, committing fraud, breach of contract, unjust enrichment, and more and would he please return their money.
