When journalist Danny Casolaro was found dead in the bathtub of his hotel room, police thought it was a suicide. But his family and colleagues believe he was murdered because he was investigating a conspiracy he called "The Octopus." It is believed to be a hidden organization linked to stolen government spy software, a series of unsolved murders and some of the biggest political scandals of the twentieth century. Years later, researcher Christian Hansen tries to unravel the secrets behind Casolaro's death and the story that killed him.
