In 2003, Harvard undergrad and computer genius Mark Zuckerberg begins work on a new concept that eventually turns into the global social network known as Facebook. Six years later, he is one of the youngest billionaires ever, but Zuckerberg finds that his unprecedented success leads to both personal and legal complications when he ends up on the receiving end of two lawsuits, one involving his former friend. As Harvard student Mark Zuckerberg creates the social networking site that would become known as Facebook, he is sued by the twins who claimed he stole their idea and by the co-founder who was later squeezed out of the business.
