Go Tell Aunt Rhodey (That Everybody's Dead)

A case has Jethro Gibbs scratching his head, and on the way to solving it falls down a rabbit hole of government conspiracies, illegal experimentation, kidnapping, cover-ups and a plot nine years in the making to expose the people responsible. In the shadows, the one who vowed to get justice for his family and those that died before him must decide if exposing himself is worth it.
