I'm sure like many I wondered what ever happened to that leak, the Panama papers. If that was your question, this has no answers, its just a puff piece on the journalists and how "heroic" they are. Very little on the corruption is covered, just hinted at superficially, not details worth mentioning, even spends an entire section just bashing Trump on pure speculation. There is neither insightful behind the scenes exploration or real coverage of cases of corruption, its a "journalism is dangerous" piece when even the cases cited may have been based on other motivations, its simply pushing a narrative, wealthy bad, Trump bad, journalists good. Most certainly nothing about the media and journalists own hand in discrediting themselves contributing to the modern medias inability to cover anything important.
The cases and trials you'd expect to be covered are only mentioned in a series of end text before the credits. A completely wasted opportunity.
